标准遗传算法，带解释，易理解。编码长度为10位，编码精度为0.0029。种群规模设为40，遗传算子分别为比例选择，单点交叉和单点变异。交叉概率0.7，变异概率0.1。-Standard genetic algorithm with explanation and easy to understand. Code length is 10 bits, the coding accuracy 0.0029. Population size is set to 40, respectively, the proportion of genetic operators selection, crossover and single-point single-point mutation. Crossover probability 0.7, mutation probability 0.1.
