Generational Computation Reduction in Informal Counterexample-Driven Genetic Programming

Thomas Helmuth, Edward Pantridge, James Gunder Frazier +1

Counterexample-driven genetic programming (CDGP) uses specifications provided as formal constraints to generate the training cases used to evaluate evolving programs. It has also b…

Leveraging Symbolic Regression for Heuristic Design in the Traveling Thief Problem

Andrew Ni, Lee Spector

The Traveling Thief Problem is an NP-hard combination of the well known traveling salesman and knapsack packing problems. In this paper, we use symbolic regression to learn useful…

Objectives Are All You Need: Solving Deceptive Problems Without Explicit Diversity Maintenance

Ryan Boldi, Li Ding, Lee Spector

Navigating deceptive domains has often been a challenge in machine learning due to search algorithms getting stuck at sub-optimal local optima. Many algorithms have been proposed t…

Particularity

Lee Spector, Li Ding, Ryan Boldi

We describe a design principle for adaptive systems under which adaptation is driven by particular challenges that the environment poses, as opposed to average or otherwise aggrega…
