Dynamic programming of 0/1 knapsack problem for network-level pavement asset management system
Bibliographic record
Abstract
For low volume roads, selecting maintenance and rehabilitation activities have become a major concern for most transportation agencies. At large-scale road networks, the combinatorial explosion of the feasible solution is a major difficulty with treatment activities programming. As part of the Wyoming Technology Transfer Center efforts to develop a comprehensive optimization analysis in Wyoming, this research study developed a user-friendly optimization algorithm, using a dynamic programming implementation of the 0/1 knapsack problem. The developed algorithm utilized the ant colony optimization algorithm, which is one of the swarm intelligence optimization sub-packages, to provide locally-optimal solutions (sub-sets) to select the optimal treatments for road networks at a large scale. Ultimately, a case study of 318 county roads in Wyoming is analyzed, and the results of different scenarios and current network performance are compared. The developed optimization algorithm helps the decision-makers in selecting the optimum set of roads that can maximize the overall pavement performance within a limited maintenance budget.

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.
