This paper studies approximating the partition function of the anti-ferromagnetic multi-state Potts model at low temperature on random regular bipartite graphs, and shows that single-site Glauber dynamics have exponentially slow mixing time but proposes a deterministic algorithm for approximation.

This paper proposes HGeo-TopoMap, a method for topological mapping in autonomous driving using an explicit prior map and implicit spatial relations, achieving substantial improvements in accuracy and robustness.
