# Consistency Trajectory Planning (CTP) Overview

Consistency Trajectory Planning (CTP) denotes a class of planning methods that impose some form of trajectory-level coherence across time, hypotheses, or optimization stages, rather than treating each local continuation, replanning cycle, or sampled future independently. In the literature, the term is used most explicitly by "Consistency Trajectory Planning: High-Quality and Efficient Trajectory Optimization for Offline Model-Based Reinforcement Learning" [2507.09534], where CTP is an offline model-based reinforcement learning method built on a Consistency Trajectory Model for fast trajectory optimization. More broadly, closely related work uses “consistency” to refer to temporal consistency in long-horizon sequence generation, consistency of successive replanned segments, common-prefix consistency across uncertain scenarios, scene consistency across jointly predicted agents, or trajectory-space consistency with geometric and kinematic feasibility [2402.04647], [2409.10310], [2206.13387], [2604.12656]. Across these variants, the central theme is that a useful planner should generate trajectories whose parts remain mutually compatible with a persistent objective, latent plan, safety envelope, or execution prefix.

## 1. Conceptual scope and problem setting

CTP arises in settings where a planner must generate or optimize trajectories under long horizons, uncertainty, multimodality, or repeated replanning. The unifying concern is that locally valid trajectory fragments may fail to combine into a globally coherent plan. In long-horizon offline reinforcement learning, this appears as **temporal consistency** under finite-context autoregressive modeling: a model may predict plausible local continuations while failing to preserve a coherent episode-level objective [2402.04647]. In receding-horizon motion planning, it appears as inconsistency between consecutive replanned segments, such as unstable terminal states, discontinuous velocity or acceleration evolution, and oscillatory behavior under frequent regeneration [2602.21691]. In autonomous driving under partial observability, it appears as branch-switching across environment hypotheses unless candidate trajectories share a common executable prefix [2409.10310].

The literature therefore does not define CTP through a single universal formalism. Instead, several operational notions recur. One is **single-plan persistence**, in which all local decisions are conditioned on one latent or mode variable fixed over the episode or rollout [2402.04647], [2502.19908]. Another is **adjacent-segment compatibility**, where new trajectory segments are regularized to align with previous segment endpoints or momentum evolution [2602.21691]. A third is **shared-prefix consistency**, where trajectories optimized for different environment hypotheses must agree over an initial segment before diverging [2409.10310]. A fourth is **scene consistency**, where multi-agent futures must be jointly compatible rather than sampled independently per agent [2206.13387]. A fifth is **trajectory-space feasibility consistency**, where geometric continuity, curvature regularity, kinematic executability, and drivable-area compliance are treated as coupled properties of the clean trajectory itself [2604.12656].

The explicit named method CTP in offline model-based reinforcement learning adopts a trajectory-level planning view of reinforcement learning. It learns a generative model over future state trajectories from an offline dataset and plans by sampling candidate trajectories and executing the first action in a receding-horizon style [2507.09534]. Its motivation is the high computational cost of diffusion planning, which requires many denoising steps. CTP addresses this by replacing iterative denoising with a consistency-distilled trajectory generator capable of one-step or few-step planning [2507.09534].

## 2. Explicit CTP in offline model-based reinforcement learning

The most direct source for the term is the offline model-based reinforcement learning method introduced in [2507.09534]. The paper considers an MDP
\[
M=\left \{ S,A,P,R,\gamma ,d_{0}  \right \},
\]
with objective
\[
\mathbb{E} \left [  {\textstyle \sum_{k=0}^{k_{end} }\gamma^k r\left (s_{k},a_{k}  \right )    \right ].
\]
Rather than directly learning a reactive policy, it learns a generative model over future state trajectories and performs planning by sampling candidate trajectories, scoring them, and recovering the first action through inverse dynamics [2507.09534].

The core modeling object is the **Consistency Trajectory Model (CTM)**. A pretrained diffusion-style trajectory model serves as teacher, and the student CTM is trained to perform “anytime-to-anytime” transitions along the probability flow ODE. The student parameterization is
\[
G_{\boldsymbol{\theta}\left(\mathbf{x}_t, t, w\right)=\frac{w}{t} \mathbf{x}_t+\left(1-\frac{w}{t}\right) g_{\boldsymbol{\theta}\left(\mathbf{x}_t, t, w\right).
\]
Here \(\mathbf{x}_t\) is a noisy trajectory at noise level \(t\), and \(w \le t\) is the target lower noise level [2507.09534]. This differs from standard diffusion planners by allowing direct jumps across time levels rather than only adjacent reverse steps.

The training procedure begins with a teacher diffusion model trained via
\[
\mathcal{L}({\boldsymbol{\phi}):= \mathbb{E}_{\sigma \sim p_{train},\tau \sim \mathcal{D},n \sim \mathcal{N}(0,{\sigma }^{2}\mathrm {I}    )}\left[ \left \| D_{\boldsymbol{\phi} }(\mathbf{x}_{\sigma }(\tau),\sigma)-\mathbf{x}_0(\tau) \right \|_{2}^{2}   \right].
\]
Distillation uses a second-order Heun solver over the teacher’s probability flow ODE, together with a consistency trajectory loss, a denoising score matching regularizer, and an optional GAN loss [2507.09534]. The final objective is
\[
\mathcal{L} = \mathcal{L}_{\mathrm{CTM} + \lambda_{\mathrm{DSM} \mathcal{L}_{\mathrm{DSM} + \lambda_{\mathrm{GAN} \mathcal{L}_{\mathrm{GAN}.
\]

At inference, CTP samples future state trajectories from Gaussian noise using one or a few CTM jumps,
\[
\mathbf{x}_{t_{n} \gets G_{\boldsymbol{\theta}(\mathbf{x}_{t_{n+1}, t_{n+1}, {t_{n}),
\]
scores them with a critic trained by
\[
\mathcal{L}_{\text{critic}(\alpha)=\mathbb E_{\tau\sim \mathcal D}\big[(V_\alpha(\mathbf x_{t_0}(\tau))-R_k)^2\big],
\]
and recovers the first action using inverse dynamics,
\[
\mathcal{L}({\boldsymbol{\varphi}):= \mathbb{E}_{(s_k,a_k,s_{k+M}) \sim \mathcal{D}  }\left[\left \|a_k-h_{\boldsymbol{\varphi}(s_k,s_{k+M})  \right \|_{2}^{2}\right].
\]
This yields a planning pipeline consisting of **state-trajectory generation + critic selection + inverse dynamics**, rather than Q-guided denoising [2507.09534].

Experimentally, the method is strongest in long-horizon, goal-conditioned tasks. On Maze2D, it reports \(154.1 \pm 2.3\) on U-Maze, \(167.1 \pm 2.4\) on Medium, and \(216.7 \pm 3.4\) on Large, with an average of \(179.3\), compared with Diffuser \(119.5\), CP \(121.2\), and RACTD \(133.4\) [2507.09534]. On Kitchen, it reports \(74.5\pm0.3\) on mixed and \(91.2\pm1.0\) on partial, for an average of \(82.85\) [2507.09534]. On AntMaze, it reports an average of \(83.33\) versus LEQ \(61.18\) [2507.09534]. The paper also emphasizes inference efficiency: Diffuser with \(N=20\) requires about \(1900\) ms per sample, while CTP with \(N=1\) requires about \(15\) ms, corresponding to roughly \(120\times\) speedup [2507.09534]. By contrast, it is not uniformly best on locomotion or Adroit, which suggests that CTP as defined there is especially advantageous in sparse-reward, long-horizon trajectory planning rather than all offline RL settings [2507.09534].

## 3. Latent-plan and autoregressive forms of consistency

A major adjacent line of work formulates consistency through persistent latent variables or modes. The clearest example is the Latent Plan Transformer (LPT), which addresses planning from offline trajectory-return pairs \((\tau,y)\) without step-wise rewards [2402.04647]. LPT introduces a latent plan \(z \in \mathbb{R}^d\) with factorization
\[
p_{\theta}(\tau, y, z) = p_{\alpha}(z) p_\beta(\tau|z) p_\gamma(y|z),
\]
where the trajectory model is a finite-context autoregressive Transformer
\[
p_\beta(\tau|z) = \prod_{t=1}^H p_\beta(\tau_{(t)}|\tau_{(t-K)}, ..., \tau_{(t-1)}, z),
\]
and the return model is
\[
p_{\gamma}(y|z) = \mathcal{N}(r_\gamma(z), \sigma^2).
\]
Training is by maximum likelihood on trajectory-return pairs, with posterior inference over a single latent plan for the whole episode using Langevin dynamics [2402.04647].

The crucial CTP-relevant statement is that posterior inference over \(z\) “naturally gathers sub-trajectories to form a consistent abstraction despite the finite context” [2402.04647]. This is reflected in the posterior score decomposition
\[
\nabla_{z_0} \log p_\theta(z_0|\tau, y) =\nabla_{z_0}\log p_0(z_0) +\nabla_{z_0}\log p_\gamma(y|U_\alpha(z_0)) +\sum_{t=1}^H\nabla_{z_0}\log p_\beta(\tau_{(t)}|\tau_{(t-K:t-1)},U_\alpha(z_0)).
\]
The last term aggregates all finite-context sub-trajectory likelihoods across the episode [2402.04647]. Consistency here is therefore **implicit consistency through latent posterior coupling**, rather than an explicit hand-designed consistency loss.

A related but distinct formulation appears in CarPlanner, a reinforcement-learning planner for autonomous driving that uses a fixed mode variable across autoregressive rollout [2502.19908]. The paper contrasts a vanilla autoregressive policy with a “consistent auto-regressive planner” that conditions all future ego actions on a single mode \(\boldsymbol c\) chosen from the initial state:
\[
\rho_0(\boldsymbol{s}_0) \prod_{t=0}^{T-1} \underbrace{P(s^{1:N}_{t+1} | \boldsymbol{s}_t)}_{\text{World Model} \int_{\boldsymbol{c} \underbrace{P(\boldsymbol{c} | \boldsymbol{s}_0)}_{\text{Mode Selector} \prod_{t=0}^{T-1} \underbrace{\pi(a_t | \boldsymbol{s}_t, \boldsymbol{c})}_{\text{Policy}   d\boldsymbol{c}.
\]
The consistency claim is that a constant mode variable prevents the trajectory from switching intent mid-rollout [2502.19908]. In ablation, the consistent framework with displacement-error reward reaches \(94.07\) CLS-NR, versus \(86.89 \pm 0.28\) for the vanilla framework, and richer longitudinal-lateral mode structure further improves performance [2502.19908]. This suggests a narrower but practically important CTP interpretation: consistency as persistence of behavioral mode across autoregressive planning steps.

## 4. Replanning consistency and local segment compatibility

A second major interpretation of CTP concerns **successive replanning cycles** rather than long-horizon latent abstraction. In visually impaired assistive navigation, a trajectory generation method with endpoint regulation and momentum-aware dynamics addresses precisely this problem [2602.21691]. The planner works in a Frenet frame around a reference path \(\mathbf r(s)\), with state
\[
\boldsymbol{\xi}(t) = [s,\dot{s},\ddot{s},d,\dot{d},\ddot{d}]^\top,
\]
and quintic longitudinal and lateral parameterizations
\[
s(t) = \sum_{i=0}^{5} a_i t^i, \qquad d(s) = \sum_{i=0}^{5} b_i s^i.
\]
The method’s consistency mechanisms are **endpoint regulation** and **momentum-aware dynamics** [2602.21691].

Endpoint regulation defines a terminal-state consistency prior over sampled candidates:
\[
\boldsymbol{\eta}(t_\tau) = [\dot{s},\ddot{s},\dot{d},\ddot{d}]^\top,
\]
\[
\mathcal{R}_{\mathrm{ep}\!\left(\boldsymbol{\xi}(t_\tau)\right) = \left\| \boldsymbol{W}_{\mathrm{ep} \left( \boldsymbol{\eta}_i(t_\tau) - \boldsymbol{\eta}_{\mathrm{ref}(t_\tau) \right) \right\|^2.
\]
A spacing bound
\[
\left\| \boldsymbol{\xi}_i(t_\tau) - \boldsymbol{\xi}_{i-1}(t_\tau) \right\| \le \Delta_0
\]
further regularizes endpoint dispersion [2602.21691]. Momentum-aware optimization uses
\[
\mathcal{J}_i = \int_{t_0}^{t_\tau} L_i(t)\,\mathrm{d}t + \lambda_{\mathrm{ep} \, \mathcal{R}_{\mathrm{ep}\!\left(\boldsymbol{\xi}(t_\tau)\right),
\]
with
\[
L_i(t) = \frac{1}{2} m_i \|v_i(t)\|^2 - \boldsymbol{F}_{\text{ext}(t)\!\cdot\! v_i(t)} + \lambda_s \|\dot{v}_i(t)\|^2 + \lambda_u\,\Psi_u(t).
\]
The term \(\lambda_s \|\dot v_i(t)\|^2\) suppresses momentum change, thereby regularizing acceleration evolution across segment boundaries [2602.21691]. This is a local, adjacent-segment notion of consistency rather than an episode-level or scenario-tree notion.

A different replanning-consistency mechanism appears in "Globally Guided Trajectory Planning in Dynamic Environments" [2303.07751]. There, multiple topologically distinct trajectories are constructed in space-time, and **topology information is propagated across planning iterations** so the robot does not chatter between alternatives. The planner represents topological equivalence via a function
\[
\mathcal{H}(\tau_i,\tau_j,\mathcal{O}) = \begin{cases} 1 & \tau_i,\tau_j \text{ topologically equivalent},\\ 0 & \text{otherwise}. \end{cases}
\]
Segment IDs \(\alpha_i\) and trajectory IDs \(\beta_i\) are propagated through time-shifted graph reuse, and switching is discouraged by a selection cost
\[
\begin{aligned}
J_{\mathrm{select} = &\sum_{i\in\mathcal{I} w_L \|p_i-p_{i-1}\| + w_V \big|\,\|v_i\|-\bar{v}\big| \\
&+ w_a \alpha^{i}\|a_i\| + w_c C,
\end{aligned}
\]
where \(C\) is a penalty if the trajectory was not selected in the previous iteration [2303.07751]. This is a pragmatic graph-based form of CTP in which consistency means persistence of behavioral class across replans.

## 5. Shared-prefix and multi-scenario consistency under uncertainty

A particularly direct CTP formulation appears in autonomous driving under partial observability via **consistent parallel trajectory optimization** [2409.10310]. The planner considers multiple possible obstacle configurations \(o^{(j)} \in \mathcal O\), generates one candidate trajectory per hypothesis, and enforces that all trajectories share a common initial segment. This shared segment is represented by a consensus condition:
\[
\varphi(\mathbf{x}^{(0)}_{t_k,[1:N_s]})   = \varphi(\mathbf{x}^{(1)}_{t_k,[1:N_s]}) = \dots = \varphi(\mathbf{x}^{(N_c-1)}_{t_k,[1:N_s]}),
\]
where \(\varphi\) extracts position, velocity, acceleration, and orientation variables over the prefix [2409.10310]. The state is augmented for smoothness and higher-order bounds:
\[
\mathbf{x} = [p_x\quad p_y \quad \theta \quad \dot{\theta} \quad v \quad a_x\quad a_y\quad j_x\quad j_y ]^T.
\]

Safety is modeled by a discrete-time barrier function over scenario-conditioned trajectories. The safe set for trajectory \(j\) is
\[
\mathcal{C}^{(j)} := \{\mathbf{s}^{(j)}_{t_k,[0,N]} \in \mathcal{T}_j^\mathcal{K} \mid \mathbf{h}(\mathbf{s}^{(j)}_{t_k,[0,N]}, o^{(j)}) \geq \mathbf{0}\},
\]
and the consensus-safe set is
\[
\mathcal{C}_{cons} = \bigcap_{j=0}^{N_c-1} \mathcal{C}_{cons}^{(j)} \subseteq \mathcal{C}_{h}.
\]
Under the paper’s Theorem 1, if each trajectory satisfies the spatiotemporal safety constraints and the prefix consensus condition, then \(\mathcal{C}_{cons}\) is forward invariant [2409.10310]. This is one of the clearest formal guarantees for CTP-like safety: the shared prefix is jointly safe across all modeled hypotheses, while suffixes may diverge by scenario.

The optimization is solved with consensus ADMM. Scenario-specific Bézier control points are updated in parallel, while global consensus variables \(\mathbf Y_x,\mathbf Y_y,\mathbf Y_\theta\) are updated by averaging:
\[
\mathbf{Y}^{\iota+1}_{x} [:,j] =   \frac{1}{N_c} \sum_{i=0}^{N_c-1} \mathbf{A}^T_{\text{cons},x}  \mathbf{C}^{\iota+1}_x [:,i],
\]
with analogous updates for \(y\) and \(\theta\) [2409.10310]. In dense uncertain obstacle navigation, CPTO reports \(0\%\) collision rate and \(72.88\) ms runtime; in NGSIM cruising it reports \(e_{\text{mae}} = 0.0493\), compared with \(0.1240\) for BPHTO and \(0.1601\) for Batch-MPC [2409.10310]. This supports the interpretation of CTP as **safe shared-prefix planning across uncertainty branches**.

A related but generative version appears in the predictive planner with consistency models [2502.08033]. That method samples joint ego-and-neighbor futures from a learned consistency model conditioned on ego goal, then refines ego trajectories with online gradient guidance under constraints such as goal reaching, acceleration limit, and yaw-rate-like \(\omega\)-limit [2502.08033]. Its consistency notion is different: denoising outputs at nearby noise scales should map to the same clean multi-agent trajectory,
\[
\mathcal L_{\text{consistency} = \mathbb E_{i,\epsilon} \Bigl[ d\bigl(f_\theta(x_i,y,\sigma_i)-f_\theta(x_{i+1},y,\sigma_{i+1})\bigr) \Bigr].
\]
Yet in practical planning terms it also belongs to the broader CTP family, because it generates whole interactive futures rather than independent one-step actions and supports online constraint injection [2502.08033].

## 6. Geometry, feasibility, and scene consistency

Another important branch of CTP-related work treats consistency as compatibility between the generated trajectory and the geometric or physical structure of the environment. FeaXDrive is exemplary in this regard [2604.12656]. It argues that diffusion planners trained in a noise-centric parameterization are poorly aligned with the actual planning object, which is the clean future trajectory \(x_0\). The planner therefore predicts \(\hat x_0\) directly at each diffusion step:
\[
\hat{x}_0 = f_{\theta}(x_t, t, c),
\]
with base loss
\[
\mathcal{L}_{x_0} = \left\|\hat{x}_0 - x_0\right\|_2^2.
\]
This “trajectory-centric” reformulation is then combined with adaptive curvature-constrained training, drivable-area guidance during reverse sampling, and feasibility-aware GRPO post-training [2604.12656].

The curvature feasibility loss is
\[
L_{\mathrm{fea} = \frac{1}{T}\sum_{i=1}^{T} \max\!\left(|\kappa_i|-\kappa_i^{\mathrm{adp},0\right)^2,
\]
with adaptive curvature threshold
\[
\kappa_i^{\mathrm{adp} = \min\!\left(\kappa_{\max}^{\mathrm{geo},\ \frac{a_{\max}^{\mathrm{lat}{v_i^2+\epsilon_v}\right).
\]
Drivable-area guidance uses a signed distance field and footprint-level barrier loss during reverse diffusion [2604.12656]. This yields a structured notion of consistency spanning geometry, dynamics, and map compliance. Reported curvature violation rates are \(0.88\%\) for FeaXDrive-IL and \(2.40\%\) for FeaXDrive with feasibility-aware GRPO, compared with \(8.59\%\) for DiffusionDrive and \(15.5\%\) for ReCogDrive with GRPO [2604.12656]. In this reading, CTP is less about a persistent latent or prefix and more about **trajectory-space self-consistency**.

Scene consistency in multi-agent prediction provides another complementary notion. ScePT models joint trajectory distributions over cliques of interacting agents and explicitly regularizes collision compatibility [2206.13387]. Its joint latent distribution takes a Gibbs/factor-graph form
\[
\log \mathbb{P}(\mathbf{z}) \propto \sum_i f_i(x_i,z_i) + \sum_{e_{ij}\in\mathcal{E} f_{ij}(x_i,x_j,z_i,z_j),
\]
and futures are generated by policy rollout with differentiable dynamics, rather than independent per-agent decoding [2206.13387]. The paper reports much lower collision rate than Trajectron++, and with collision regularization the collision rate becomes virtually zero [2206.13387]. This suggests that a planner’s contingency set should itself be consistent as a joint multi-agent world evolution, not merely a product of individually plausible tracks.

Finally, classical geometric planning work can also be read through a CTP lens. The Frenet-based method using dynamic curvature identifies failures of the usual assumption that the planned trajectory continuously follows the reference curve, and proposes the validity condition
\[
\kappa d < 1
\]
to avoid discontinuous projection, skipped reference segments, and self-intersection [2012.14617]. The sequential linear programming method for vehicle-dimension-constrained path planning similarly seeks consistency between body geometry, kinematics, steering limits, and corridor occupancy by optimizing a spatial path with explicit rectangle-footprint constraints rather than point-mass approximations [1704.06325]. These works do not use the CTP label, but they address geometric forms of trajectory consistency that remain central in narrow or highly constrained environments.

## 7. Comparative structure, misconceptions, and limitations

The literature suggests that “Consistency Trajectory Planning” is best treated as a family resemblance concept with at least four major realizations.

| CTP interpretation | Representative mechanism | Representative papers |
|---|---|---|
| Latent or mode consistency | Single latent or mode conditions the whole rollout | [2402.04647], [2502.19908] |
| Replanning consistency | Endpoint, momentum, or topology propagation across replans | [2602.21691], [2303.07751] |
| Shared-prefix consistency | Multiple hypothesis-conditioned plans share a common safe prefix | [2409.10310] |
| Feasibility / scene consistency | Trajectory remains internally feasible and externally compatible | [2604.12656], [2206.13387] |

A common misconception is that CTP always refers to consistency models in the generative-model sense. That is too narrow. The explicit offline RL method CTP indeed uses a Consistency Trajectory Model [2507.09534], and driving work such as ConsistencyPlanner uses fast-sampling consistency models for real-time multimodal waypoint generation [2606.11569]. ConsistencyPlanner defines a one-step conditional denoising policy
\[
\pi_{\theta}(a|s) \triangleq f_{\theta}(a^{t}, t, s) = c_{skip}(t)a^{t} + c_{out}(t)F_{\theta}(a^{t},t|s),
\]
with \(15\) ms inference versus \(122\) ms for a 10-step diffusion baseline, and OR/CR/PR of \(2.09/2.77/93.72\) on Waymax [2606.11569]. But many equally relevant CTP works do not use generative consistency models at all.

A second misconception is that CTP implies a single explicit consistency regularizer. In fact, many of the strongest examples enforce consistency structurally or inferentially rather than with a named penalty. LPT uses a single latent plan inferred from all sub-trajectories and the final return [2402.04647]. CarPlanner uses a fixed rollout mode [2502.19908]. CPTO uses equality constraints on a shared prefix [2409.10310]. ScePT uses joint latent structure, dynamics-aware rollout, and collision regularization [2206.13387]. The relevant question is often not whether a regularizer exists, but where the coupling is introduced.

A third misconception is that consistency means rigidity. Several papers explicitly show the opposite. In LPT, the low-level autoregressive policy adapts to observed state while remaining guided by the same latent plan [2402.04647]. In Connect Four, LPT scores \(0.99 \pm 0.01\), matching ESPER and surpassing DT’s \(0.8 \pm 0.07\), which the paper interprets as maintaining a stable plan while responding to contingencies [2402.04647]. In CPTO, candidate trajectories can diverge after the consensus prefix [2409.10310]. Thus CTP generally aims at **coherent flexibility**, not open-loop determinism.

Limitations recur across formulations. Implicit consistency mechanisms often lack explicit guarantees: LPT’s temporal consistency is inferred through posterior coupling rather than hard constraint or theorem [2402.04647]. Scenario-based consistent-prefix planning depends on the completeness of the hypothesis set \(\mathcal O\) and a strong sensing assumption [2409.10310]. Replanning-consistency methods may improve only local adjacent-segment compatibility rather than global optimality [2602.21691]. Trajectory-centric feasibility methods can trade off one consistency dimension against another, as drivable-area guidance may improve DAC while slightly increasing curvature violations [2604.12656]. And the explicit CTP method in offline RL is not uniformly best in all domains, particularly dense-reward locomotion [2507.09534].

Taken together, these results suggest a practical synthesis. CTP is best understood as planning under an added requirement that trajectory parts, hypotheses, or generated modes remain mutually compatible with a persistent structure: a latent plan, a shared prefix, a feasible corridor, a scene-consistent joint future, or a physically grounded trajectory manifold. The exact named method in offline model-based reinforcement learning [2507.09534] is a specific and influential instance, but the broader research landscape shows that consistency is a general organizing principle for planning under long horizons, multimodality, uncertainty, and repeated replanning.
