PuLP

PuLP is an LP (Linear Programming) modeler written in Python. It simplifies the creation of linear and mixed-integer programming optimization problems, allowing users to define problems using Pythonic syntax. It can generate MPS or LP files and call various open-source (like GLPK, COIN-OR CBC, HiGHS, SCIP) or proprietary (CPLEX, GUROBI, MOSEK, XPRESS) solvers to find optimal solutions. The current version is 3.3.0, and it is actively maintained with regular updates.
