1 简介
学生心理学优化算法（Student psychology based optimization algorithm，SPBO）是于2020 提出的一种基于学生向往提高成绩的心理提出的新颖智能优化算法。
In this article, a new metaheuristic optimization algorithm (named as, student psychology based optimization(SPBO)) is proposed. The proposed SPBO algorithm is based on the psychology of the students who are trying togive more effort to improve their performance in the examination up to the level for becoming the best student inthe class. Performance of the proposed SPBO is analyzed while applying the algorithm to solve thirteen 50dimensional benchmark functions as well as fifteen CEC 2015 benchmark problems. Results of the SPBO iscompared to the performance of ten other state-of-the-art optimization algorithms such as particle swarm optimization, teaching learning based optimization, cuckoo search algorithm, symbiotic organism search, covariantmatrix adaptation with evolution strategy, success-history based adaptive differential evolution, grey wolf optimization, butterfly optimization algorithm, poor and rich optimization algorithm, and barnacles mating optimizer. For fair analysis, performances of all these algorithms are analyzed based on the optimum results obtained as well as based on convergence mobility of the objective function. Pairwise and multiple comparisons areperformed to analyze the statistical performance of the proposed method. From this study, it may be establishedthat the proposed SPBO works very well in all the studied test cases and it is able to obtain an optimum solutionwith faster convergence mobility.
