遗传算法，模拟达尔文进化论的自然选择和遗产学机理的生物进化构成的计算模型，一种不断选择优良个体的算法。谈到遗传，想想自然界动物遗传是怎么来的，自然主要过程包括染色体的选择，交叉，变异（不明白这个的可以去看看生物学），这些操作后，保证了以后的个基本上是最优的，那么以后再继续这样下去，就可以一直最优了。利用遗传算法，实现三维点云的配准。(Genetic algorithm, a computational model that simulates the biological evolution of Darwin's evolutionary theory of natural selection and inheritance mechanism, is an algorithm that continuously chooses good individuals. When it comes to inheritance, think about how animal inheritance comes from in nature. The main natural processes include chromosome selection, crossover, mutation (if you don't understand this, you can look at biology). These operations ensure that the next one is basically optimal, and then continue to do so in the future, you can always be optimal.)
