Reluplex: An Efficient SMT Solver for Verifying Deep Neural Networks
TLDR
Results show that the novel, scalable, and efficient technique presented can successfully prove properties of networks that are an order of magnitude larger than the largest networks verified using existing methods.

Satisfiability Modulo Theories
TLDR
This chapter provides a brief overview of SMT together with references to the relevant literature for a deeper study and an alternative approach in which a SAT solver is integrated with a separate decision procedure for conjunctions of literals in the background theory.

The SMT-LIB Standard Version 2.0
TLDR
This paper introduces Version 2 of the SMT-LIB Standard, a major upgrade of the previous Version 1.2 which, in addition to simplifying and extending the languages of that version, includes a new command language for interfacing with SMT solvers.
CVC Lite: A New Implementation of the Cooperating Validity Checker Category B
We describe a tool called CVC Lite (CVCL), an automated theorem prover for formulas in a union of first-order theories. CVCL supports a set of theories which are useful in verification, including…

Handbook of Satisfiability
TLDR
The number of particles in the solution is likely to increase, but the amount of particles bound to cover the solution will not increase as much as previously thought.

A DPLL(T) Theory Solver for a Theory of Strings and Regular Expressions
TLDR
A set of algebraic techniques for solving constraints over the theory of unbounded strings natively, without reduction to other problems are presented and implemented in the SMT solver cvc4 to expand its already large set of built-in theories to a theory of strings with concatenation, length, and membership in regular languages.

CVC: A Cooperating Validity Checker
TLDR
The CVC ("Cooperating Validity Checker") decision procedure is described, which implements a framework for combining subsidiary decision procedures for certain logical theories into a decision procedure for the theories' union.

The Marabou Framework for Verification and Analysis of Deep Neural Networks
TLDR
Marabou is an SMT-based tool that can answer queries about a network’s properties by transforming these queries into constraint satisfaction problems, and it performs high-level reasoning on the network that can curtail the search space and improve performance.

Validity Checking for Combinations of Theories with Equality
TLDR
This paper presents the algorithm used in the Stanford Validity Checker (SVC) which has been used to aid several realistic hardware verification efforts and presents the results of initial experiments in which SVC is used as a decision procedure in PVS, resulting in dramatic speed-ups.

Checking Satisfiability of First-Order Formulas by Incremental Translation to SAT
TLDR
This paper describes an alternative but similar approach to using SAT in conjunction with a more expressive fragment of first-order logic, however, rather than translating the entire formula up front, the formula is incrementally translated during a search for the solution.
