目前,当我调用ClpSolver.Solve()时,我得到的输出如下所示Clp0000I Optimal - objective value -1e-12 这对于单个解决方案来说不是什么大问题,但是当我在循环中调用它时, 浏览0提问于2021-06-04得票数 1 1回答 MiniZinc模型的优化 、、、 我有一个应该找到d1的MiniZinc模型。N和o1..k,0.N使得xk = ok...

this leads to round-off errors. Any LP solver will have to perform operations on this data that can amplify the problem. In some cases like your problem, this can make the solver conclude that the problem is infeasible when it isn't. When you fix...
Clp是一个solver,Coin-or团队又为python开发了一个包叫CyLP(https://github.com/coin-or/CyLP) ,可以直接用来调用他们家的求解器 (CLP, CBC, and CGL),所以下面讲讲怎么装CyLP。 windows平台:直接pip install cylp,会自动安装clp等求解器。 linux平台:比较麻烦,需要用conda先安装cbc等求解器,具体方法参照CyLP...
Clp (Coin-orlinearprogramming) is an open-source linear programming solver. It is primarily meant to be used as a callable library, but a basic, stand-alone executable version is also available. It is designed to find solutions of mathematical optimization problems of the form ...
The implementation contains abyte-code compilerand a built-inconstraintsolver which deals with linear arithmetic and contains a mechanism for delayingnonlinearconstraints until they become linear. Since CLP(R) is a superset ofPROLOG, the system is also usable as a general-purposelogic programminglangua...

Apart from exchanging bounds for variables and objective, little is known of what constitutes a good hybrid model and how a hybrid solver can utilize the complementary strengths of inference and relaxations. This paper adds to the field by identifying constraints as the essential link between CLP ...
