Abstract

fetched live from OpenAlex

One of the main challenges when designing constraint based systems in general and those involving temporal constraints in particular, is the ability to deal with conditional constraints and composite variables. Indeed, in this particular case the set of variables involved by the constraint problem to be solved is not known in advance. More precisely, while some variables (called initial variables) are available in the initial problem, others are added dynamically to the problem during the resolution process via activity constraints and composite variables. Activity constraints allow some variables to be activated (added to the problem) when activity conditions are true. Composite variables are variables whose values are the possible variables each composite variable can take. We propose a method based on constraint propagation for solving efficiently constraint problems involving numeric and symbolic temporal constraints, composite variables and activity constraints. We call these latter problems conditional and composite temporal constraint satisfaction problems (CCTCSPs). Experimental evaluation conducted on randomly generated CCTCSPs demonstrates the efficiency of our method to solve these problems especially when using the forward check strategy during the search.

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.
