docplex

问题 I build my mathematical model using DOcplex IBM package for Python. I am sure that the other part of the modeling is correct, however when the call to Model.solve() is executed, and I get the following error: "CPLEX DLL not found: please provide DOcplexcloud credentials" I have CPLEX Studio 12.6 installed on my pc, and I want to solve the problem locally not on cloud. 回答1: It sounds like you do not have the CPLEX Python API "installed". By default, when you install CPLEX Optimization Studio

问题 What is the difference between Docplex and CPLEX Python API? Is any of them faster than the other? 回答1: The CPLEX Python API is a lightweight wrapper around the C API (aka, the C Callable Library). As such, it provides access to nearly all of the functionality CPLEX has to offer. Variables and constraints are identified by their indices in the matrix. docplex is an object oriented modeling API that is numpy/pandas friendly, which may be more natural to work with. The model can be solved
