Enhance System-2 Global Selection with Flexible Graph Traversal and Planning

Develop more flexible graph traversal and planning mechanisms for the System-2 Global Selection process in Mnemis’s hierarchical graph to go beyond the current top-down selection and improve deliberate, structured retrieval.

Background

Mnemis’s System-2 Global Selection currently performs a top-down, layer-by-layer traversal over a hierarchical graph of categories to retrieve structurally relevant memory items. This design aims to complement similarity-based retrieval by providing a global, deliberate selection mechanism.

The authors identify as an open direction the enhancement of global selection with more flexible traversal and planning mechanisms, suggesting the need for richer search strategies to improve coverage and reasoning over the hierarchy.
