The weak structural balance(WSB) theory is suitable to solve the weak structure balance problem of most signed networks, and it is an NP-hard problem. Here a WSB evolutionary algorithm(WSB-EA) is proposed, which computes the global unbalanced degree of signed network based on evolutionary algorithm. In this method, the energy function of WSB theory is used as the fitness function. First, a heuristic method is used to initialize the population. After the tournament selection, single crossing, single point va...
