We use the token dropping game as a tool to design an efficient distributed algorithm for stable orientations and more generally for locally optimal semi-matchings. The prior work by Czygrinow et al. (DISC 2012) finds a stable orientation in O(Δ^5) rounds in graphs of maximum degree Δ, while we improve it to O(Δ^4) and also prove a lower bound of Ω(Δ). For the more general problem of locally optimal semi-matchings, the prior upper bound is O(S^5) and our new algorithm runs in O(C · S^4) rounds, which is an improvement for C = o(S); here C and S are the maximum degrees of customers and servers, respectively."}],"arxiv":1,"project":[{"_id":"26A5D39A-B435-11E9-9278-68D0E5697425","name":"Coordination in constrained and natural distributed systems","grant_number":"840605","call_identifier":"H2020"}],"oa":1,"scopus_import":"1","publisher":"Association for Computing Machinery","fulldoi":"https://doi.org/10.1145/3409964.3461785","_id":"9678","publication_identifier":{"isbn":["9781450380706"]},"publication":"Annual ACM Symposium on Parallelism in Algorithms and Architectures","month":"07","date_published":"2021-07-06T00:00:00Z","publication_status":"published","related_material":{"record":[{"relation":"earlier_version","status":"public","id":"15074"}]},"user_id":"2DF688A6-F248-11E8-B48F-1D18A9856A87","article_processing_charge":"No","department":[{"_id":"DaAl"}],"das_tickbox":"1","ec_funded":1,"citation":{"chicago":"Brandt, Sebastian, Barbara Keller, Joel Rybicki, Jukka Suomela, and Jara Uitto. “Efficient Load-Balancing through Distributed Token Dropping.” In <i>Annual ACM Symposium on Parallelism in Algorithms and Architectures</i>, 129–39.
