Contractible configurations, Z3-connectivity, Z3-flows and triangularly connected graphs
Tutte conjectured that every 4-edge connected graph admits a nowhere-zero Z3-flow and Jaeger, Linial, Payan and Tarsi conjectured that every 5-edge connected graph is Z3-connected. In this paper, we characterize the triangularly connected graphs G that are Γ-connected for any Abelian group Γ with |Γ| ≥ 3. Therefore, these two conjectures are verified for the family of triangularly connected gra...
متن کاملDegree condition and Z3-connectivity
Let G be a 2-edge-connected simple graph on n ≥ 3 vertices and A an abelian group with |A| ≥ 3. If a graph G is obtained by repeatedly contracting nontrivial A-connected subgraphs of G until no such a subgraph left, we say G can be A-reduced to G. Let G5 be the graph obtained from K4 by adding a new vertex v and two edges joining v to two distinct vertices of K4. In this paper, we prove that fo...
متن کاملEngineering Theories with Z3
Modern Satisfiability Modulo Theories (SMT) solvers are fundamental to many program analysis, verification, design and testing tools. They are a good fit for the domain of software and hardware engineering because they support many domains that are commonly used by the tools. The meaning of domains are captured by theories that can be axiomatized or supported by efficient theory solvers. Nevert...
متن کاملProofs and Refutations, and Z3
Z3 [3] is a state-of-the-art Satisfiability Modulo Theories (SMT) solver freely available from Microsoft Research. It solves the decision problem for quantifier-free formulas with respect to combinations of theories, such as arithmetic, bit-vectors, arrays, and uninterpreted functions. Z3 is used in various software analysis and test-case generation projects at Microsoft Research and elsewhere....
متن کاملKonrad Zuses Z3 in Detail
Konrad Zuse built the machine Z3 from 1939 to 1941 in the Methfesselstraße 7 in BerlinKreuzberg with some friends and a small support by the government. With the Z3 Konrad Zuse wanted to show, that it is possible to build a reliable working machine for very complicated arithmetic calculations, which is freely programmable and is based on a binary floating point number and switching system. For ...
