PuLP is a Python library for modeling linear and mixed integer programming (LP/MILP) problems. It lets users define optimization models with variables, objectives, and constraints, then solves them via external solvers such as CBC, GLPK, HiGHS, Gurobi, CPLEX, and others.

Use cases

• solve linear programming problems in python
• model mixed integer programming problems
• optimize resource allocation and blending problems
• solve transportation and production planning problems
• generate MPS or LP model files for solvers
• solve sudoku or set partitioning as an optimization problem
• use gurobi cplex or cbc from python

When to choose

• you need to formulate and solve LP or MILP models in Python
• you want a pure-Python modeling layer that works with many open-source and commercial solvers
• you need to export models as MPS or LP files

When to avoid

• you need nonlinear or general constraint programming without CP-SAT
• you want a solver bundled out of the box without installing CBC or another solver separately
• you need large-scale optimization with a modeling DSL beyond Python
