A Simple Analysis of Ranking in General Graphs (2511.08801v1)
Published 11 Nov 2025 in cs.DS
Abstract: We provide a simple combinatorial analysis of the Ranking algorithm, originally introduced in the seminal work by Karp, Vazirani, and Vazirani [KVV90], demonstrating that it achieves a $(1/2 + c)$-approximate matching for general graphs for $c \geq 0.005$.
