Based on the combining of the quantum evolutionary algorithms (QEA) with the main mechanisms of clone
an improved evolutionary algorithmquantum clonal evolutionary strategies (QCES) was proposed in this paper.By adopting the high-effective parallelism of QEA and replacing clone operator by mutation and selection of the classical evolutionary algorithms (CEA)
it has better diversity and the converging speed than CEA and avoided prematurity.The convergence of the QCES is proved and its superiority is shown by experiments in this paper.
