Revolutionizing AI: SMT Meets ILP for Advanced Rule Learning
This paper introduces a modular SMT-ILP framework that couples PyGol (an ILP system) with Z3 (an SMT solver) to address limitations of classical ILP in handling numerical constraints. The framework separates structural rule learning from numerical parameter instantiation and verification, allowing for the induction of hybrid rules that combine symbolic predicates with learned numerical constraints (thresholds, intervals, multi-literal arithmetic). Experiments on synthetic datasets demonstrate its ability to extend symbolic rule learning expressivity, complementing prior numerical ILP approaches, particularly in linear, relational, nonlinear, and multi-hop reasoning domains.

Background Refinement
| Feature | Classical ILP | SMT-ILP (PyGol-Z3) |
|---|---|---|
| Numerical Constraints | Limited (discretization) | Extensive (linear, nonlinear, intervals) |
| Relational Patterns | Strong | Strong, with numerical refinement |
| Predicate Invention | Yes (symbolic only) | Yes (symbolic + numerical thresholds) |
| Modularity | Low (tightly coupled) | High (separate ILP/SMT components) |
Unlocking Nonlinear Geometric Concepts
The framework successfully learned rules for complex shapes like circles and parabolas (Geometry3), which are inherently inaccessible to traditional ILP. This demonstrates the power of SMT solvers to handle nonlinear arithmetic within a symbolic rule learning context.
