I'm new to cvxpy. Installed cvpxy using following command conda install -c conda-forge lapack conda install -c cvxgrp cvxpy But while I'm trying to run the code knapsack_problem.solve(solver=cvxpy.GLPK_MI), I'm getting error message Solv...
It is necessary to import python-scip in your code. This is achieved by including the line Create a solver instance. Access the methods in thescip.pxifile using the solver/model instancemodel, e.g.: Writing new plugins The Python interface can be used to define custom plugins to extend th...
The developed mathematical model is a MILP problem defined by all three types of variables: continuous, binary and integer. The model itself was developed using MATLAB and solved with a non-commercial MILP solver SCIP, from the OPTI toolbox [30]. Due to the limitation of computational power,...

MiniZinc is a free and open-source constraint modeling language. You can use MiniZinc to model constraint satisfaction and optimisation problems in a high-level, solver-independent way, taking advantage of a large library of pre-defined constraints. Your model is then compiled into FlatZinc, a sol...
As another alternative solver, SCIP may be used. In the following, you will find installation instructions for the individual solvers.CPLEXTogether with Gurobi, CPLEX is the perfect choice for computing strain designs. Its stability and support of advanced features like indicator constraints and ...

The simulation is run on a Windows-based server with an Intel Core i7 processor rated at 2.40 GHz and 256 GB of installed memory RAM. The SCIP solver is used to solve the problem. The data on the electric smart home system and the data on the EV used in this paper are shown in Tab...
