Induction in saturation-based theorem proving automates inductive reasoning for first-order properties with inductively defined data types and beyond.
Zusammenfassung
Introduction
Induction is crucial for automating reasoning in formal verification.
Recent advances in inductive reasoning open up new possibilities for automation.
Relation to the State-of-the-Art
Integrating induction directly into saturation-based approaches enhances efficiency.
First-order provers complement SMT solvers in reasoning with theories and quantifiers.
Preliminaries
Standard multi-sorted first-order logic with equality is assumed.
Functions, predicates, variables, and Skolem constants are defined.
Saturation-Based Theorem Proving
First-order provers saturate input clauses to compute logical consequences.
Superposition calculus is commonly used for inference.
Saturation with Induction
Induction inference rules are applied directly in the saturation process.
New inference rules capture inductive steps and optimize theorem proving.
Induction with Term Algebras
Structural induction and well-founded induction schemata are introduced.
Recursive function definitions are used for inductive reasoning.
Multi-Clause Induction
Generalization of induction rules for multiple clauses is proposed.
Extensions of Inductions in Saturation
Induction with generalization and rewriting with induction hypotheses are introduced.
Integer Induction
Upward and interval upward induction rules for integers are defined.
