資源簡介

測試可以跑，根據(jù)自己情況修改下函數(shù)即可. NSGA-III 首先定義一組參考點(diǎn)。然后隨機(jī)生成含有 N 個(gè)（原文獻(xiàn)說最好與參考點(diǎn)個(gè)數(shù)相同）個(gè)體的初始種群，其中 N 是種群大小。接下來，算法進(jìn)行迭代直至終止條件滿足。在第 t 代，算法在當(dāng)前種群 Pt的基礎(chǔ)上，通過隨機(jī)選擇，模擬兩點(diǎn)交叉（Simulated Binary Crossover，SBX）和多項(xiàng)式變異 產(chǎn)生子代種群 Qt。Pt和 Qt的大小均為 N。因此，兩個(gè)種群 Pt和 Qt合并會形成種群大小為 2N 的新的種群 Rt=Pt∪Qt。 為了從種群 Rt中選擇最好的 N 個(gè)解進(jìn)入下一代，首先利用基于Pareto支配的非支配排序?qū)?Rt分為若干不同的非支配層（F1，F(xiàn)2等等）。然后，算法構(gòu)建一個(gè)新的種群St，構(gòu)建方法是從 F1開始，逐次將各非支配層的解加入到 St，直至 St的大小等于 N，或首次大于 N。假設(shè)最后可以接受的非支配層是 L層，那么在 L+ 1 層以及之后的那些解就被丟棄掉了，且 St\ FL中的解已經(jīng)確定被選擇作為 Pt+1中的解。Pt+1中余下的個(gè)體需要從 FL中選取，選擇的依據(jù)是要使種群在目標(biāo)空間中具有理想的多樣性。
