Often GP evolves side effect free trees. These pure functional expressions can be evaluated in any order. In particular they interpreted from the genetic modification point outwards. Incremental evaluation exploits fact that: highly evolved children semantic difference between child and parent falls with distance syntactic disruption (e.g. crossover point) reach zero before whole has been inter...

In machine learning, ensemble techniques are widely used to improve the performance of both classification and regression systems. They combine models generated by different learning algorithms, typically trained on data subsets or with parameters, obtain more accurate models. Ensemble strategies range from simple voting rules complex effective stacked approaches. based adopting a meta-learner,...
