Update to Isabelle2024

Update to Isabelle2024

This repository has been updated to Isabelle2024. However, we have received reports that the integration of Sledgehammer with this repository is now less stable under Isabelle2024. Therefore, although we have confirmed that the Abduction Prover works in some cases, its performance may currently be suboptimal. We are working to resolve this issue as quickly as possible. 🙇

For users seeking the best performance, we recommend using Isabelle2023 and this version of the Abduction Prover (v0.2.7-alpha), which was developed specifically for Isabelle2023."

Abduction Prover October 2023

What's new?

In this release, we:

• Introduced Best-First Expansion based on the number of available processes,
• Improved stability,
• Fixed many bugs,
• Switched to a strategy that applies PSL strategies to new conjectures more aggressively,
• Reintroduced Nitpick into Abduction Prover, and
• Enhanced the function to filter out unpromising conjectures.

Our small experiment based on this release confirmed that this version can automatically prove the following TIP problems: Prof01, Prod06, Prod11, Prod16, Prod21, Prod26, Prod31, Prod36, Prod41, and Prod46."
