Abstract

fetched live from OpenAlex

We present a framework for a guided parallel cooperative search that combines common meta-heuristics to solve combinatorial problem with more robustness and efficiency. Based on the central memory concept, the proposed identification pattern mechanism sends information to individual meta-heuristics about promising and unpromising patterns of the solution space. By fixing or prohibiting specific solution attribute values in particular search methods, we can focus the search to desired regions. This mechanism may thus be applied to enforce a better coordination between the individual methods and control the diversification and intensification of the global search. We apply this mechanism to the Vehicle Routing Problem with Time Windows. Experimental results on an extended set of benchmark problem sets illustrate the benefits of the proposed methodology.

Full frame distilled prediction

Teacher imitation

Not 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.
