An improved Branch-and-cut code for the maximum balanced subgraph of a signed graph
Rosa Figueiredo, Yuri Alexandre Rodrigues Frota · arXiv (Cornell University) · 2013
The Maximum Balanced Subgraph Problem (MBSP) is the problem of finding a subgraph of a signed graph that is balanced and maximizes the cardinality of its vertex set. We are interested in the exact solution of the problem: an improved version of a branch-and-cut algorithm is proposed. Extensive computational experiments are carried out on a set of instances from three applications previously discussed in the literature as well as on a set of random instances.
