We evolve floating point Sextic polynomial populations of genetic programming binary trees for up to a million generations. We observe continued innovation but this is limited by tree …
It is 30 years since John R. Koza published “Jaws”, the first book on genetic programming [Genetic Programming: On the Programming of Computers by Means of Natural Selection …

With side effect free terminals and functions it is possible to evaluate the fitness of genetic programming trees from their parents without creating them. This allows selection before …

Figure 2 shows a large nested function composed of floating point arithmetic operations (+,- ,× and÷). Each function acts as a two input information funnel and loses information. The red …

We inject a random value into the evaluation of highly evolved deep integer GP trees 9 743 720 times and find 99.7% of test outputs are unchanged. Suggesting crossover and …
For the goal of automatically evolving Embodied Intelligence (EI), we investigate an open software architecture inspired by the high surface area to volume ratio of animal lungs …
Information theory explains the robustness of deep GP trees, with on average up to 83.3% of crossover run time disruptions failing to propagate to the root node, and so having no impact …
Information-theoretic analysis of large, evolved programs produced by running genetic programming for up to a million generations has shown even functions as smooth and well …

We sample the genetic programming tree search space and show it is smooth, since many mutations on many test cases have little or no fitness impact. We generate uniformly at …
