Abstract

fetched live from OpenAlex

Games present sophisticated challenges and require intricate reasoning. Quantified Boolean Formulas enjoy a natural game-theoretic semantics and are therefore a promising representation for games. However, game solving with current QBF solvers is challenging. In this paper, we use QBF solvers’ reasoning capabilities to search for a specific kind of winning strategy, restricting the allowed moves. While this could, in principle, prevent the discovery of a winning strategy, when there are only more complex ones, we experimentally show that our method does indeed find a winning strategy when one is found by the current best QBF encoding. Furthermore, we also show that this reduction in available moves allows to reduce solving time across QBF solvers and preprocessors.

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.
