DEC-POMDPs have been studied with finite-horizon and infinite-horizon discounted-sum objectives, and there exist solvers both for exact and approximate solutions. In this work we consider Goal-DEC-POMDPs, where given a set of target states, the objective is to ensure that the target set is reached with minimal cost. We consider the indefinite-horizon (infinite-horizon with either discounted-sum, or undiscounted-sum, where absorbing goal states have zero-cost) problem. We present a new method to solve the problem that extends methods for finite-horizon DEC- POMDPs and the RTDP-Bel approach for POMDPs. We present experimental results on several examples, and show our approach presents promising results."}],"oa":1,"year":"2015","ddc":["000"],"publication_identifier":{"issn":["2664-1690"]},"user_id":"2DF688A6-F248-11E8-B48F-1D18A9856A87","file_date_updated":"2020-07-14T12:46:53Z","page":"16","oa_version":"Published Version","file":[{"file_size":378162,"date_updated":"2020-07-14T12:46:53Z","creator":"system","content_type":"application/pdf","date_created":"2018-12-12T11:53:14Z","file_id":"5475","checksum":"8542fd0b10aed7811cd41077b8ccb632","file_name":"IST-2015-326-v1+1_main.pdf","relation":"main_file","access_level":"open_access"},{"date_updated":"2020-07-14T12:46:53Z","file_size":64,"creator":"dernst","content_type":"text/plain","date_created":"2019-04-16T13:00:33Z","checksum":"84c31c537bdaf7a91909f18d25d640ab","file_id":"6317","relation":"main_file","access_level":"closed","file_name":"IST-2015-326-v1+2_authors.txt"}],"status":"public"}
