On Cafesat: A Modern SAT Solver for Scala

Régis William Blanc

We present CafeSat, a SAT solver written in the Scala programming language. CafeSat is a modern solver based on DPLL and featuring many state-of-the-art techniques and heuristics. It uses two-watched literals for Boolean constraint propagation, conflict-dr ...

Fabrication-aware Design with Intersecting Planar Pieces

Mark Pauly, Yuliy Gennadievich Schwartzburg

We propose a computational design approach to generate 3D models composed of interlocking planar pieces. We show how intricate 3D forms can be created by sliding the pieces into each other along straight slits, leading to a simple construction that does no ...

Qualitative Spatial and Temporal Reasoning with Answer Set Programming

Jingshi Li

Representing and reasoning spatial and temporal information is a key research issue in Computer Science and Artificial Intelligence. In this paper, we introduce tools that produce three novel encodings which translate problems in qualitative spatial and te ...

Efficient State Merging in Symbolic Execution

George Candea, Johannes Kinder, Volodymyr Kuznetsov, Stefan Bucur

Symbolic execution has proven to be a practical technique for building automated test case generation and bug finding tools. Nevertheless, due to state explosion, these tools still struggle to achieve scalability. Given a program, one way to reduce the num ...

Sets with Cardinality Constraints in Satisfiability Modulo Theories

Viktor Kuncak, Philippe Paul Henri Suter, Robin Steiger

Boolean Algebra with Presburger Arithmetic (BAPA) is a decidable logic that can express constraints on sets of elements and their cardinalities. Problems from verification of complex properties of software often contain fragments that belong to quantifier- ...

Scala to the Power of Z3: Integrating SMT and Programming

Viktor Kuncak, Philippe Paul Henri Suter

We describe a system that integrates the SMT solver Z3 with the Scala programming language. The system supports the use of the SMT solver for checking satisfiability, unsatisfiability, as well as solution enumeration. The embedding of formula trees into Sc ...

Satisfiability Modulo Recursive Programs

Viktor Kuncak, Philippe Paul Henri Suter, Ali Sinan Köksal

We present a semi-decision procedure for checking satisfiability of expressive correctness properties of recursive first-order functional programs. In our approach, both properties and programs are expressed in the same language, a subset of Scala. We impl ...

On an Efficient Decision Procedure for Imperative Tree Data Structures

Viktor Kuncak

We present a new decidable logic called TREX for expressing constraints about imperative tree data structures. In particular, TREX supports a transitive closure operator that can express reachability constraints, which often appear in data structure invari ...

Verification of consensus algorithms using satisfiability solving

André Schiper

Consensus is at the heart of fault-tolerant distributed computing systems. Much research has been devoted to developing algorithms for this particular problem. This paper presents a semi-automatic verification approach for asynchronous consensus algorithms ...
