Abstract
We are concerned with the synthesis of strategies for sequential decision-making in non-deterministic dynamical environments where the objective is to satisfy a prescribed temporally extended goal. We frame this task as a Fully Observable Non-Deterministic planning problem with the goal expressed in Linear Temporal Logic (LTL), or LTL interpreted over finite traces (LTLf). While the problem is well-studied theoretically, existing algorithmic solutions typically compute so-called strong-cyclic solutions, which are predicated on an assumption of fairness. In this paper we introduce novel algorithms to compute so-called strong solutions, that guarantee goal satisfaction even in the absence of fairness. Our strategy generation algorithms are complemented with novel mechanisms to obtain proofs of unsolvability. We implemented and evaluated the performance of our approaches in a selection of domains with LTL and LTLf goals.

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
