Experimental study on performance of engineering-oriented optimization algorithms

Twelve Benchmark optimization-testing functions were used to study performance of ten engineering-oriented optimization algorithms. The twelve benchmark functions consisted of continuous function, discontinuous function, convex function, concave function, unimodal function, multimodal function, quadratic function, non-quadratic function, low-dimensional function, high-dimensional function, function with constraints and function without constraints. Based on the analysis of experimental results, characteristics of theses algorithms are summarized and criterions for selecting optimal algorithm are put forward.
