由于大多数真实符号网络更满足弱结构平衡理论,并且求解符号网络的弱结构平衡问题是NP难问题,因此提出了基于进化算法的符号网络弱结构平衡计算方法——WSB-EA算法。该方法将弱结构平衡定理的能量函数作为适应值函数,首先利用启发式的方法初始化种群,经过锦标赛选择、单路交叉、单点变异、局部搜索4个阶段,迭代有限次之后得到最优解。在此算法中,提出了大型符号网络的存储方法和增量计算方式。通过大量实验,WSB-EA算法得出了4个小型符号网络和2个大型符号网络的弱不平衡度。并且与其他算法相比,WSB-EA算法能更快收敛得到最优解,具有较高鲁棒性。

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 variation, and local search, the optimal solution is obtained after a finite number of iterations. The algorithm involves a storage of large signed network and incremental calculation. Through several experiments, the weak unbalanced degree of four small signed networks and two large signed networks are derived from WSB-EA algorithm. Compared with other algorithms, the WSB-EA algorithm can converge to the optimal solution faster and has a higher robustness.
