Abstract

fetched live from OpenAlex

Model checking is a formal verification technique that plays a crucial role in software engineering in ensuring the correctness of a system. Declarative models are a useful method of expressing the description of a software system during the early stages of development. However, one of the major challenges in model checking of declarative models is the state-space explosion problem. We introduce the idea of structured state-space exploration (S3E), a novel approach to combat state-space explosion in hierarchical transition systems. The motivating idea behind this approach is to utilize the structure of the model found in the user's description, such as the control state hierarchy or guards and actions on the transitions, to derive abstractions that can lead to a reduction in the number of states and/or transitions in the model at the Kripke structure level of description of the model. The proposed methodologies are implemented and evaluated on Dash+ models.

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.
