pymoo is an open-source Python framework for single-, multi-, and many-objective optimization, offering state-of-the-art algorithms like NSGA-II, NSGA-III, MOEA/D, GA, DE, CMA-ES, and PSO. It also includes problem definitions, visualization, parallelization, and decision-making tools for the full optimization workflow.

Use cases

• run NSGA-II on a multi-objective optimization problem in Python
• compute a Pareto front for an engineering design problem
• solve constrained optimization problems with evolutionary algorithms
• apply differential evolution or CMA-ES to a single-objective function
• benchmark algorithms on ZDT, DTLZ, or WFG test problems
• visualize and analyze convergence of optimization runs
• parallelize objective function evaluations across cores

When to choose

• you need evolutionary multi-objective optimization in Python
• you want a mature, well-documented library with many algorithms and test problems
• you need visualization, decision making, and parallel evaluation in one framework

When to avoid

• you need gradient-based or convex optimization solvers
• you work outside Python or need a GUI-driven tool
• your problem is small enough for scipy.optimize
