What is a genotype repair bias in Genetic Algorithms?
Updated May 16, 2026
Short answer
Repair bias occurs when repaired solutions systematically distort the search space.
Deep explanation
When infeasible solutions are corrected using repair operators, the repaired outputs may bias the search toward certain regions of the solution space. This can reduce diversity and unintentionally favor specific structures.
Real-world example
Scheduling systems that always push tasks earlier, skewing results.
Common mistakes
- Assuming repair operators are neutral transformations.
