There are two opposite types which are interpreted as friendship vs. enmity or trust vs. distrust between people. The aforementioned social network structure can be represented by a signed graph, where people are the graph¡¯s vertices and their interactions are graph¡¯s edges. The edges can be positive and negative signs. To determine trustworthiness, this paper considers the problem of a signed graph partitioning with minimizing the sum of the negative edge's weight and balanced size of its clusters. An efficient algorithm to solve such a problem is proposed. The experimental results show that the proposed algorithm outperforms in terms of the execution times and the accuracy within the given bounds %K graph partition %K min-cuts %K signed graphs %K social networks %K social ties %U https://hrcak.srce.hr/index.php?show=clanak&id_clanak_jezik=333668
