What is crowding replacement strategy?

Updated May 16, 2026

Short answer

Crowding replaces individuals with similar offspring to preserve diversity.

Deep explanation

In crowding, offspring compete with similar individuals rather than the entire population. This preserves niches and prevents dominant individuals from taking over the population too quickly.

Real-world example

Maintaining diversity in product recommendation systems.
