Abstract
The design of metaheuristics for numerical and combinatorial optimization suffers from an explosion of techniques. Many of these techniques can be described by the same pseudo-code in which the method of generating new search solutions changes, but the overall technique follows a standard Evolutionary Computation or Swarm Intelligence framework. The benefit of new metaphors for the design of metaheuristics has been called into question by prominent members of the research community. However, the benefit of metaphors in their entirety remains largely unquestioned. A new experimental analysis of a foundational metaheuristic demonstrates behaviours that are distinctly different from its metaphor-based inspiration. It appears that detailed analysis has been superseded by the general assumption that an algorithm will behave in accordance to the metaphor it has been designed to mimic. The ability of a metaphor-based design to misguide the analysis and observation of its operation represents a key danger in the use of metaphors to design metaheuristics.

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
