查询词典 chromosome

To take advantage of the chaotic mapping, a repetition prepotency evolution algorithm with a population initialized by chaotic numbers is developed in which the chaotic mapping is an uncommon seeding-machine to produce different initial'chromosome'populations never appeared before for PE algorithm. The combination of chaotic mapping and PE makes PECA be able to probe lots of optima rapidly and effectively owing to the quick convergence speed of PE and relatively high population diversity guaranteed by chaotic mapping.

结合混沌来初始化优势进化算法的群体成员，还设计了基于混沌初始化群体成员的循环优势进化方法，该方法在混沌保证每次优势进化绝对不同的初始群体成员的情况下，不仅具有了优势进化的快速收敛优点而且有混沌映射保证群体成员的高度多样性，从而可以快速探测很多局部最优点，大大提高了找到全局最优点的机会，用它训练神经网络预测四卤化物振动频率研究充分体现了该策略的优越性。
