Nettet18. feb. 2024 · The linear sum assignment problem is also known as minimum weight matching in bipartite graphs. A problem instance is described by a matrix C, where each C[i,j] is the cost of matching vertex i of the first partite set (a “worker”) and vertex j of the second set (a “job”).
Nettetproblem 4.1 Introduction The linear sum assignment problem (LSAP) is one of the most famous problems in linear programming and in combinatorial optimization. Informally speaking, we are given an n×n cost matrix C =(c ij) and we want to match each row to a different column in such a way that the sum of the corresponding entries is minimized. city nails in la habraNettet30. aug. 2016 · I have a problem of assigning 7 possible workers to 3 machines.
