主问题 meaning in Chinese

master problem
primal problem

A mathematic model with time penalty function for the vehicle - scheduling problem built in this paper is divided into two sub - problems of clustering and routing
本文针对有时间窗的车辆调度问题，建立了含有时间惩罚函数的数学模型，并将之分解为分群主问题和巡回子问题两个求解过程。
2 . this paper advanced mixed integer nonlinear programming ( minlp ) algorithms mixed with constraint programming ( cp ) to solve industrial process hybrid model mixed with logical rule . cp methods have proved to be successful in solving highly constrained discrete optimization and feasibility problems . it can effectively solve hybrid model mixed with logical rule by integrating cp , nonlinear programming and mixed integer linear programming
本文针对结合逻辑的工业过程混杂模型，提出了结合约束程序( cp )的混合整数非线性规划( mfnlp )算法，采用cp方法求解模型的可行点，并采用milp cp方法求解算法中的milp主问题，通过计算实例可看出，采用这种算法比采用通用的转化成minlp方法的计算时间大为减少。
