Reviews: Monte-Carlo Tree Search for Constrained POMDPs

WebAn extension called constrained POMDP is introduced to model risk explicitly and generate plans with bounded-risks as the world changes [Undurti and How2010, Poupart et al.2015]. Using a similar idea, a chance-constrained POMDP (CC-POMDP) is proposed to include a more flexible definition of risk allocation and studied in different problem ... WebJul 12, 2008 · Such problems can be modeled as chance-constrained POMDP's (CC-POMDP's). Our first contribution is a systematic derivation of execution risk in POMDP domains, which improves upon how chance constraints are handled in the constrained POMDP literature. Second, we present RAO*, a heuristic forward search algorithm … christy report
