Abstract

fetched live from OpenAlex

Heuristic search is a core area of Artificial Intelligence with applications to planning, scheduling and game playing. Real-time heuristic search applies to search problems where plan execution needs to start before a complete solution can be computed. Since the inception of real-time heuristic search in the early 1990s a great number of algorithms have been proposed and evaluated. In this paper we break them down into building blocks and conduct a search in the space of such building blocks. Even simple tabulated and iterative searches find new real-time heuristic search algorithms outperforming manually crafted contemporary algorithms.

Fetched live from OpenAlex and de-inverted. Abstracts are not stored in this database: the inverted indexes are 8.6 GB of the frame’s 9.3 GB of text, and the host has 13 GB free.

Not 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.
