ABSTRACT
Signed graphs have various applications, ranging from analyzing social situations, portfolio risk hedging, and clustering data. Many of these applications rely on balancing the corresponding signed graph. This talk will focus on exact methods to accomplish this by reducing the size of the signed graph, and by decomposing the signed graph into smaller instances. The results and effects of these approaches will be given for some data-inspired graphs as well as random instances to show that these approaches give high-quality solutions.
