On Synergies between Diversity and Task Decomposition in Constructing Complex Systems with GP
Bibliographic record
Abstract
Complexity in genetic programming is unfortunately often associated with undesirable properties such as code bloat. In this work, we review developments in which complex systems are promoted through: 1) the evolution of teams of programs, and then 2) the context specific reuse of previously evolved code. To do so, two classes of diversity are identified: intra-team diversity and inter-team diversity. Intra-team diversity promotes task decomposition/cooperative coevolution between multiple programs, i.e. teams of programs. A fundamental requirement is that programs can learn context. Inter-team diversity is promoted through maintaining model and task diversity during evolution. The combination of both result in the ability to identify teams of programs and associate them with specific contexts, and then organize teams of programs hierarchically so solve multiple tasks. Finally, the concept of cumulative population wide performance is used to illustrate how inter model diversity in particular introduces useful biases into the types of solutions evolved.

Full frame machine prediction
Teacher imitationNot calibrated prevalence, not ground truth. Human validation pending. The Gemma side is a direct model label for every work in the frame, read from the title-only record. The Codex side is a classifier learned from the 10,348 direct Codex labels and calibrated to design-weighted sample rates; fields without enough sample support carry no Codex call. Candidate is the union of the two sides; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human labels.

Machine scores (provisional)
The two teacher heads of the student model, read on this work. A score orders the frame for review; it never asserts a category, and the validation status ships verbatim with every row.
Baseline scores from an immature model (maturity gate not passed, 7 training rounds). Scores rank; they never assert a category.
score_only:v0-immature-baseline · verbatim from the scoring run: score_only means the number may rank works, and no category label ships from itClassification
machine, unvalidatedMachine predicted; a candidate call from one source (direct Gemma or distilled Codex), not a consensus.
