Official implementation of paper "Learning to Dispatch for Job Shop Scheduling via Deep Reinforcement Learning"
Hello! I noticed that the code did not include PDRS related codes such as SPT , MOPNR mentioned in the experiment part of the paper. Is that so?

尊敬的作者： 您好！ 我阅读了您的代码，对于permissinleLS.py中的函数，我有一些疑问，恳请您的解答： 1.mch_a = np.take(mchMat, a) - 1 这一语句的含义。在该模块中，机器数减一的语句大量出现，并且相关变量常出现在矩阵索引的位置，例如 opIDsOnMchs[mch_a][np.where(opIDsOnMchs[mch_a] >= 0)][-1]。我不太能理解其含义，在我的理解下，np.take(mchMat, a)提取了某一个action对应的机器编号，似乎和行索引没有什么关联。 2.变量opIDsOnMchs的含义。 3.对于action和Job工序中顺序约束的理解。通篇阅读后，我认为您对action的编码方式是 J * M，例如15 * 15的数据中共有编号为0-224的225个action。然而permissinleLS.py测试代码的输出结果print('opIDsOnMchs\n', opIDsOnMchs) 动摇了我的理解。例如在某一次完整的迭代中最终opIDsOnMchs输出为[[3 1 8] [0 4 6] [2 5...
