Our contributions are twofold: (1) First we show that the algorithmic question is reducible to the problem of a logarithmic number of min-plus matrix multiplications of n×n-matrices, where n is the number of vertices of the graph. (2) Second, when the weights are nonnegative, we present the first (1+ε)-approximation algorithm for the problem and the running time of our algorithm is Õ(nωlog3(nW/ε)/ε),1 where O(nω) is the time required for the classic n×n-matrix multiplication and W is the maximum value of the weights. With an additional O(log(nW/ε)) factor in space a cycle with approximately optimal weight can be computed within the same time bound.","lang":"eng"}],"issue":"C","type":"journal_article","status":"public","scopus_import":"1","year":"2014","arxiv":1,"oa":1,"date_updated":"2025-09-29T13:17:21Z","doi":"10.1016/j.tcs.2014.06.031","month":"08","title":"Approximating the minimum cycle mean","publication":"Theoretical Computer Science","date_created":"2018-12-11T11:51:40Z","user_id":"317138e5-6ab7-11ef-aa6d-ffef3953e345","intvolume":"       547","article_type":"original","publisher":"Elsevier","citation":{"mla":"Chatterjee, Krishnendu, et al. “Approximating the Minimum Cycle Mean.” <i>Theoretical Computer Science</i>, vol. 547, no.
