## What it is
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

## Facets
- artifact type: library
- maturity: active
- function: math, sdk
- domain: mathematics, performance
- platform: python, cross-platform
- tags: linear-programming, mixed-integer-programming, optimization, operations-research, solver-interface, mps, lp-files, algorithms
