多班级交互式教学优化算法
Multi-Classes Interaction Teaching-Learning-Based Optimization Algorithm
摘要
Abstract
To improve the low precision and poor stability of Teaching-Learning-Based Optimization(TLBO)algorithm, a Multi-Classes Interaction Teaching-Learning-Based Optimization(MCITLBO)is proposed. On the basis of TLBO, a new clustering partition based on Euclidean distance is firstly introduced to facilitate the population effectively search in the feasible neighbor region which can strengthen the local search ability of the algorithm and strive a balance between exploration and exploitation. Two information sharing scheme is introduced to improve the learning styles of students so as to increase information exchange in the evolution and avoid the premature convergence and stagnation behavior of subgroups. Numerical experiments on six unconstrained functions, four constrained functions and one engineering design problem called the tension string design problem show that MCITLBO outperforms the other algorithms in precision and stability.关键词
