Kinga Varga: Optimisation of the clustering of signed graphs

Signed graphs contain different types of relations towards actors in SNA. The assignment of a positive or negative relationship finds its roots in structural balance theory. The mathematical formalization of this concept was later added by Harary (1953) and Cartwright ( 1956, 1979). The generalisation specify subgroups with similar characteristics related to their links to other actors in the network. Subdividing actors into prespecified homogeneous blocks provides for the analysis of such network data related to internal and external characteristics.
