Purpose

Assist in constructing formal correctness proofs for algorithms using standard proof techniques.

Capabilities

  • Proof structure templates (induction, contradiction, etc.)
  • Step-by-step proof guidance
  • Termination argument generation
  • Proof review and validation
  • Identify proof gaps

Target Processes

  • correctness-proof-testing
  • algorithm-implementation

Proof Techniques

Mathematical Induction

  • Base case identification
  • Inductive hypothesis formulation
  • Inductive step construction

Proof by Contradiction

  • Assumption negation
  • Logical derivation
  • Contradiction identification

Loop Invariant Proofs

  • Invariant specification
  • Three-part proof (init, maintenance, termination)

Structural Induction

  • For recursive data structures
  • Base case (leaf/empty)
  • Inductive case (composite)
