Prove termination of algorithms and programs using ranking functions and well-founded orderings

General

What this skill does


# Termination Analyzer

## Purpose

Provides expert guidance on proving termination of algorithms through ranking functions, well-founded orderings, and automated analysis.

## Capabilities

- Identify ranking/variant functions automatically
- Prove well-founded orderings
- Handle mutual recursion
- Detect potential non-termination
- Generate termination certificates
- Analyze complex control flow

## Usage Guidelines

1. **Structure Analysis**: Identify recursive calls and loop structures
2. **Ranking Function**: Find or construct appropriate ranking function
3. **Ordering Proof**: Prove well-foundedness of the ordering
4. **Certificate Generation**: Generate formal termination proof
5. **Non-termination Detection**: Flag potential infinite loops

## Tools/Libraries

- AProVE
- T2
- Ultimate Automizer
- SMT solvers
