An Orthogonal QUasi-Affine TRansformation Evolution (O-QUATRE) Algorithm for Global Optimization

Abstract

In this paper, a new Orthogonal QUasi-Affine TRansformation Evolution (O-QUATRE) algorithm was proposed for global optimization. The O-QUATRE algorithm is actually implemented as a combination of both the QUATRE algorithm and the orthogonal array, both of which together secured an overall better performance on complex optimization problems. The proposed algorithm is verified under CEC2013 test suite for real-parameter optimization. The experimental results indicated that the proposed O-QUATRE algorithm obtained better mean and standard deviation of fitness error than QUATRE algorithm, which means that the O-QUATRE algorithm was of more robustness and better stability.
