NettetThe 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. In other words, we want to Nettet18. feb. 2024 · The linear sum assignment problem is also known as minimum weight matching in bipartite graphs.
