Abstract
Differential Evolution (DE) is a simple yet powerful population-based metaheuristic algorithm to solve global optimization problems. In this paper, a novel differential evolution is proposed based on the competition among candidate solutions. In the proposed algorithm, the candidate solutions are divided into two groups including losers and winners based on a competition among candidate solutions. Winners generate new candidate solutions based on the DE's standard mutation and crossover operators, whereas losers learn from the winners. To this end, both crossover and mutation are changed for the loser ones. Competition is not performed in each iteration. In this regard, a new control parameter representing the competition period is introduced. We assess the performance of the proposed algorithm on CEC2017 benchmark functions with three dimensions of 30, 50, and 100. The experimental results verify the effectiveness of the proposed algorithm on the majority of the benchmark functions.

Full frame distilled prediction
Teacher imitationNot calibrated prevalence, not ground truth. Human validation pending. Learned from the 10,348 direct Codex labels and 10,348 direct Gemma labels. Candidate is the union of thresholded teacher heads; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human labels or direct frontier model 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 it
