The supported LOCAL is at least as strong as the usual LOCAL model, and as a corollary this also gives a new, short and elementary proof that shows that the round complexity of the sinkless orientation problem in the deterministic LOCAL model is Ω(log n).","lang":"eng"}],"department":[{"_id":"DaAl"}],"day":"04","license":"https://creativecommons.org/licenses/by/4.0/","type":"conference","file":[{"date_created":"2021-11-12T08:27:42Z","file_size":474242,"file_id":"10275","success":1,"date_updated":"2021-11-12T08:27:42Z","file_name":"2021_LIPIcsDISC_Korhonen.pdf","access_level":"open_access","creator":"cchlebak","content_type":"application/pdf","relation":"main_file","checksum":"c43188dc2070bbd2bf5fd6fdaf9ce36d"}],"date_updated":"2021-11-12T09:37:18Z","tmp":{"image":"/images/cc_by.png","name":"Creative Commons Attribution 4.0 International Public License (CC-BY 4.0)","short":"CC BY (4.0)","legal_code_url":"https://creativecommons.org/licenses/by/4.0/legalcode"},"article_processing_charge":"No","month":"10","file_date_updated":"2021-11-12T08:27:42Z","acknowledgement":"Janne H.
