Concurrent Planning and Execution in Lifelong Multi-Agent Path Finding with Delay Probabilities

AAAI 2025technical

In multi-agent systems, when we account for the possibility of delays during execution, online planning becomes more complicated, as both execution and planning should be able to handle delays when agents are moving. Lifelong Multi-Agent Path Finding (LMAPF) is the problem of (re)planning the collis…

Orthogonal Gradient Boosting for Simpler Additive Rule Ensembles

AISTATS 2024poster

Gradient boosting of prediction rules is an efficient approach to learn potentially interpretable yet accurate probabilistic models. However, actual interpretability requires to limit the number and size of the generated rules, and existing boosting variants are not designed for this purpose. Though…

f-Aware Conflict Prioritization & Improved Heuristics For Conflict-Based Search

AAAI 2021technical

Conflict-Based Search (CBS) is a leading two-level algorithm for optimal Multi-Agent Path Finding (MAPF). The main step of CBS is to expand nodes by resolving conflicts (where two agents collide). Choosing the ‘right’ conflict to resolve can greatly speed up the search. CBS first resolves confl…
