中文说明：测试函数是ZDT1，用matlab编写，实现了nsg2算法，亲测可用，nsga2算法优化ZDT2测试函数。收敛到Pareto最优前沿，对于从事这方面算法工作的初学者们有很大的帮助。可以借鉴学习下
English Description：
The test function is zdt1, which is written in MATLAB. Nsg2 algorithm is realized, which can be used for personal test. NSGA2 algorithm optimizes zdt2 test function. Convergence to Pareto optimal frontier is of great help to beginners who are engaged in this field. We can learn from it
