Topics
Machine learning (ML) has had a substantial impact on SAT/SMT and CP solvers, as well as automated theorem provers. Recent advances have demonstrated the power of ML to inform solver heuristics, guide proof search, and optimize algorithm portfolios. Despite growing interest in this direction, work on ML for solvers and provers is often scattered across multiple research communities – SAT, SMT, CP, theorem proving, formal methods, and machine learning – with few opportunities for focused interaction.
The ML4SP workshop aims to bring together researchers and practitioners working at the intersection of machine learning and formal reasoning systems. It provides a forum for the presentation of recent work, the exchange of ideas, and the fostering of collaboration between these communities.
Topics of interest include, but are not limited to, ML-driven approaches for:
- Heuristics (branching, restarts, …) in CP, SAT, SMT, and MIP solvers
- Tactic selection and proof guidance in automated and interactive theorem provers
- Algorithm selection, parameter tuning and algorithm configuration, and portfolio solvers
- End-to-end learning for solvers and provers
- Benchmark generation and instance hardness prediction
- Applications of ML-enhanced reasoning in verification, synthesis, planning, and related areas
- Leveraging large language models (LLMs) for solver heuristics and proof guidance
This is a 2nd year of the workshop. The 1st ML4SP workshop (invited talks only) was organized at SoCS/SAT/CP 2025 in Glasgow.
