Solution of the Maximum \(k\) -Balanced Subgraph Problem

A signed graph \(G=(V,E,s)\) is \(k\) -balanced if \(V\) can be partitioned into at most \(k\) sets in such a way that positive edges are found only within the sets and negative edges go between sets. We study the problem of finding a subgraph of \(G\) th
