Extending a Verified Simplex Algorithm

12 pagesPublished: November 18, 2018

Abstract

As an ingredient for a verified DPLL(T) solver, it is crucial to have a theory solver that has an incremental interface and provides unsatisfiable cores. To this end, we extend the Isabelle/HOL formalization of the simplex algorithm by Spasi ́c and Mari ́c. We further discuss the impact of their design decisions on the development of our extension.

Keyphrases: DPLL(T), Isabelle/HOL, Linear Rational Arithmetic, theory solver, unsatisfiable core
