Abstract

fetched live from OpenAlex

In this paper we will present a study of different res-olution techniques for solving Constraint Satisfaction Problems (CSP) in the case of temporal constraints. This later problem is called Temporal Constraint Sat-isfaction Problem (TCSP). We will mainly focus here on solving TCSPs in real time and in a dynamic en-vironment. Indeed, addressing these two issues is very relevant for many real world applications. Solving a TCSP in real time is an optimization problem that we call MTCSP (Maximal Temporal Constraint Satisfac-tion Problems). The objective function to minimize is the number of temporal constraint violations. The re-sults of the tests we have performed on randomly gen-erated MTCSPs show that the approximation method Min-Conflict-Random-Walk(MCRW) is the algorithm of choice for solving MTCSPs. Comparison study of the different dynamic arc-consistency algorithms for solving dynamic temporal constraint problems in a pre-processing phase demonstrates that the new algorithm we propose and based on a recent arc-consistency al-gorithm represents a better compromise between time and space than the other dynamic arc-consistency al-gorithms.

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.
