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."}],"user_id":"D865714E-FA4E-11E9-B85B-F5C5E5697425","page":"129-139","oa_version":"Preprint","type":"conference","article_processing_charge":"No","department":[{"_id":"DaAl"}],"publication_status":"published","quality_controlled":"1","status":"public","_id":"9678","month":"07","author":[{"full_name":"Brandt, Sebastian","last_name":"Brandt","first_name":"Sebastian"},{"first_name":"Barbara","last_name":"Keller","full_name":"Keller, Barbara"},{"first_name":"Joel","last_name":"Rybicki","id":"334EFD2E-F248-11E8-B48F-1D18A9856A87","orcid":"0000-0002-6432-6646","full_name":"Rybicki, Joel"},{"full_name":"Suomela, Jukka","first_name":"Jukka","last_name":"Suomela"},{"first_name":"Jara","last_name":"Uitto","full_name":"Uitto, Jara"}],"citation":{"ieee":"S.
