Progressive Subexpression Reuse in Symbolic Regression: Insights from RL-based Search and a Genetic Programming Realization
Reinforcement Genetic Programming is proposed, a purely GP-based and non-RL framework that explicitly realizes a stage-wise retention– reintroduction loop through a dynamically maintained subexpression pool and pool-guided population initialization, suggesting that progressive subexpression reuse is an effective mechanism for SR search.
