【摘要】 首先对遗传算法的可操作性、全局最优性、通用性及稳健性等特性进行了验证。然后针对核反应堆堆芯换料优化这一具体问题,就遗传算法的个体规模数、二进制字节数、杂交概率及变异概率等参数对解的收敛性和收敛速度的影响进行了分析。最后以先进核反应堆为例确定了遗传算法在这一具体堆芯优化计算中的优选参数值。更多还原

【Abstract】 The operability, overall optimization, generalization and stabilization of genetic algorithms are verified firstly. Pointing at the specific problems of reloading pattern of nuclear reactor core, the analy-sis has been performed for the affect of the parameters of genetic algorithms, such as the population size, the number of chromosomes, the crossover probability and the mutation probability on the convergence and convergence rate of the solutions. At last, taking the advanced nuclear reactor as the example, the op-timum seeking parameters that applied to the calculation of specific reactor core by genetic algorithms are identified.更多还原
