摘要
基于非线性优化算法的联合反演具有全局寻优、无需求偏导数、便于先验信息融入等优点。人工蜂群(ABC)算法是一种较新颖的非线性优化算法,具有独特的角色转换机制,在求解优化问题上有较强的寻优性能,但该算法也存在着搜索效率不高、局部搜索能力弱等问题。基于双种群架构可有效提高优化算法全局寻优能力。基于此,笔者提出一种双种群架构ABC算法,将交叉变异操作和最优解邻域搜索融入不同种群,选择典型的测试函数验证了改进ABC算法的有效性,并将其应用于大地电磁测深(MT)和重力数据的联合反演。模型试验和实测数据处理结果表明,双种群ABC算法具有较高的寻优能力和一定的实用性。
Joint inversion based on a non-linear optimization algorithm has the advantages of global optimization,no need to calculate partial derivatives,and convenience for the integration of prior information.As a novel non-linear optimization algorithm,the artificial bee colony(ABC)algorithm has a unique role transformation mechanism and strong performance in solving optimization problems.However,it also has some shortcomings such as low search efficiency and weak local search ability.Considering that a dual-population framework is capable of improving the global optimization performance of an optimization algorithm,we propose an ABC algorithm with a dual-population framework,in which crossover and mutation operations and neighborhood search for the optimal solution are integrated into different populations.Typical test functions are selected to verify the effectiveness of the improved ABC algorithm.Besides,the algorithm is applied into the joint inversion of magnetotelluric(MT)and gravity data.Model tests and real data feedback show that the dual-population ABC algorithm has high global optimization capability and certain practicability.
