The probability vector can be viewed as a prototype vector for generating solution vectors that have high evaluations with respect to the available knowledge of the search space. Compared with the general genetic algorithm, PBIL discards the complex and problem-correlation operators, which always affect the algorithm's performance highly.

相对于常规遗传算法，PBIL进化算法抛弃了复杂的且对算法性能影响很大的交叉、变异算子，而引入竞争学习的机制，以概率矢量的方式通过采样来产生下一代群体，然后选出群体中最优个体对概率矢量进行更新，直至最后收敛。
