“…The design optimization problem involves three continuous variables and four nonlinear inequality constraints. This problem has already been solved by many researchers, including He and Wang [14],who proposed hybrid particle swarm optimization (HPSO), Zhang et al [13],who used differential evolution with dynamic stochastic selection algorithm (DEDS) , Wang and Li [12], who proposed differential evolution with level comparison algorithm(DELC), Sadollah et al [15], who employed a mine blast algorithm(MBA), Wen et al [5], who used effective hybrid cuckoo search(HCS -LSAL), and Yang [2], who applied a cuckoo search algorithm(CS).The best solutions obtained by the above mentioned approaches are shown in Table 2.Their statistical results are shown in table 3.…”
