Abstract
This paper presents a generalization of the classic A* algorithm to the domain of sampling-based motion planning. The root assumptions of the A* algorithm are examined and reformulated in a manner that enables a direct use of the search strategy as the driving force behind the generation of new samples in a motion graph. Formal analysis is presented to show probabilistic completeness and convergence of the method. This leads to a highly exploitative method which does not sacrifice entropy. Many improvements are presented to this versatile method, most notably, an optimal connection strategy, a bias towards the goal region via an Anytime A* heuristic, and balancing of exploration and exploitation on a simulated annealing schedule. Empirical results are presented to assess the proposed method both qualitatively and quantitatively in the context of high-dimensional planning problems. The potential of the proposed methods is apparent, both in terms of reliability and quality of solutions found.

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
