Incremental evaluation is a big advantage for trajectory-based optimization algorithms. Previously, the application of similar ideas to crossover-based algorithms, such as genetic algorithms did not seem appealing as the expected benefit would be marginal. We propose the use of an immutable data structure that stores partial evaluation results inside of the solution representation, and composing new solution from parts of previously evaluated candidates, which can speed up re-evaluation. The application of this idea to the knapsack problem shows promising results hinting at logarithmic complexity in case all genetic operators can be adapted accordingly.
