Interpolation is a deductive technique applied in program analysis and verification: for example, it is used to compute over-approximations of images or refine abstractions. An interpolation system takes a refutation and extracts an interpolant by building it inductively from partial interpolants. We survey color-based interpolation systems for ground proofs produced by key inference engines of state-of-the-art solvers: DPLL for propositional logic, equality sharing for combination of convex… 
Craig Interpolation with Clausal First-Order Tableaux
We develop foundations for computing Craig-Lyndon interpolants of two given formulas with first-order theorem provers that construct clausal tableaux. Provers that can be understood in this way
Compactly Representing Uniform Interpolants for EUF using (conditional) DAGS
TLDR
Two algorithms for computing the uniform interpolant of a quantifier-free formula in EUF endowed with a list of symbols to be eliminated are proposed and correctness and completeness proofs are supplied.
The PIE Environment for First-Order-Based Proving, Interpolating and Eliminating
TLDR
The PIE system aims at providing an environment for creating complex applications of automated first-order theorem proving techniques, embedded in Prolog, and comes with a built-in default prover that can compute interpolants.
Uniform Interpolants in EUF: Algorithms using DAG-representations
TLDR
Two algorithms for computing quantifier-free uniform interpolants in the theory of equality over uninterpreted symbols ( EUF ) endowed with a list of symbols to be eliminated are proposed.

TLDR
Two algorithms for computing the uniform interpolant of a quantifier-free formula in EUF endowed with a list of symbols to be eliminated are proposed, using arguments combining rewrite techniques with model theory.

Proofs in conflict-driven theory combination
TLDR
This paper endow CDSAT with lemma learning and proof generation, and adapts the LCF approach to proofs from interactive theorem proving to conflict-driven SMT-solving and theory combination, by defining a small kernel of reasoning primitives that guarantees that C DSAT proofs are correct by construction.
On Conflict-Driven Reasoning
TLDR
A current research direction in automated reasoning is to generalize the notion of Con ict-driven satis ability to a paradigm of con icts-driven reasoning in rst-order theories for satisability modulo theories and assignments, and even in full rstorder logic for generic automated theorem proving.
Interpolation in Extensions of First-Order Logic
TLDR
A direct proof of interpolation is obtained for (classical and intuitionistic) first-order logic with identity, as well as interpolation for several mathematical theories, including the theory of equivalence relations, (strict) partial and linear orders, and various intuitionistic order theories such as apartness and positive partial andlinear orders.
Decidable fragments of first-order logic and of first-order linear arithmetic with uninterpreted predicates
TLDR
The present thesis sheds more light on the decidability boundary and aims to open new perspectives on the already known results on linear arithmetic over the rationals with uninterpreted predicates.

On Interpolation in Automated Theorem Proving
TLDR
An interpolation system for non-ground refutations is obtained, and it is proved that it is complete, if the only non-shared symbols in provisional interpolants are constants.
Towards interpolation in an SMT solver with integrated superposition
TLDR
It is shown how a first interpolation system for DPLL(Γ+T ), which integrates tightly a superposition based prover Γ in a DPLL (T ) based SMT-solver to unite their respective strengths, can be obtained from interpolation systems forDPLL, equality sharing and Γ.
Disjunctive Interpolants for Horn-Clause Verification
TLDR
A new notion of interpolation is introduced, disjunctive interpolation, which solves a more general class of problems in one step compared to previous notions of interpolant, such as tree interpolants or inductive sequences of interpolants.
Flexible interpolation with local proof transformations
TLDR
This paper presents a technique for transforming the propositional proof produced by an SMT-Solver in such a way that mixed predicates are eliminated and can be applied to allow the reuse of known interpolation algorithms.
Program analysis with interpolants
TLDR
Novel techniques for interpolation-based software model checking, an approximate method which uses Craig interpolation to compute invariants of programs and a heuristic that aims to avoid the repeated and computationally expensive construction of interpolants, thus enabling the detection of deeply buried defects such as buffer overflows.
An Interpolating Sequent Calculus for Quantifier-Free Presburger Arithmetic
TLDR
This paper introduces an interpolation approach based on a sequent calculus for QFPA that determines interpolants by annotating the steps of an unsatisfiability proof with partial interpolants, and extends the Princess theorem prover to generate interpolating proofs.

TLDR
The efficiency of Z3 makes it possible to handle problems that are beyond the reach of existing interpolating provers, as it is demonstrated using benchmarks derived from bounded verification of sequential and concurrent programs.
Exploring interpolants
TLDR
This work presents a semantic and solver-independent framework for systematically exploring interpolant lattices, based on the notion of interpolation abstraction, and discusses how interpolation abstractions can be constructed for a variety of logics, and how they can be exploited in the context of software model checking.
Ground interpolation for the theory of equality
TLDR
This paper presents a generic version of the interpolation game, parametrized by the theory T, and defines a general method to extract runs of the game from proofs in T and then generate interpolants from these runs.
Propositional Interpolation and Abstract Interpretation
TLDR
It is shown that existing interpolation algorithms are abstractions of a more general, parametrised algorithm, and reside in the coarsest abstraction that admits correct interpolationgorithms.
