What is constraint dominance in Genetic Algorithms?

Updated May 16, 2026

Short answer

Constraint dominance prioritizes feasible solutions over infeasible ones during selection.

Deep explanation

In constrained GA, solutions are ranked first by feasibility, then by fitness. A feasible solution always dominates an infeasible one, even if the latter has better objective value. This ensures constraint satisfaction is prioritized.

Real-world example

Scheduling systems where invalid schedules are never accepted.

Common mistakes

  • Ignoring feasibility leading to invalid solutions dominating search.
