Adversarial satisfiability problem [PDF]

open access: yesJournal of Statistical Mechanics: Theory and Experiment, 2011
We study the adversarial satisfiability problem, where the adversary can choose whether variables are negated in clauses or not in order to make the resulting formula unsatisfiable. This is one case of a general class of adversarial optimization problems that often arise in practice and are algorithmically much harder than the standard optimization ...

Expected number of locally maximal solutions for random Boolean CSPs [PDF]

open access: yesDiscrete Mathematics & Theoretical Computer Science, 2007
For a large number of random Boolean constraint satisfaction problems, such as random $k$-SAT, we study how the number of locally maximal solutions evolves when constraints are added.

Random Maximum 2 Satisfiability Logic in Discrete Hopfield Neural Network Incorporating Improved Election Algorithm

open access: yesMathematics, 2022
Real life logical rule is not always satisfiable in nature due to the redundant variable that represents the logical formulation. Thus, the intelligence system must be optimally governed to ensure the system can behave according to non-satisfiable ...

A Satisfiability Algorithm for Sparse Depth Two Threshold Circuits [PDF]

open access: yes, 2013
We give a nontrivial algorithm for the satisfiability problem for cn-wire threshold circuits of depth two which is better than exhaustive search by a factor 2^{sn} where s= 1/c^{O(c^2)}.

Predicting Propositional Satisfiability via End-to-End Learning

open access: yesAAAI Conference on Artificial Intelligence, 2020
Strangely enough, it is possible to use machine learning models to predict the satisfiability status of hard SAT problems with accuracy considerably higher than random guessing.

On Some Approaches to the Solution of the Problem «Useful Proof-of-work for Blockchains»

open access: yesМоделирование и анализ информационных систем, 2018
The blockchain technology is based on the ”Proof-of-work” principles. The essence of this principle is that some event (for example the bill-to-bill money transaction) becomes significant after the confirmation by a certain computer work.

Adding Path-Functional Dependencies to the Guarded Two-Variable Fragment with Counting [PDF]

open access: yesLogical Methods in Computer Science, 2017
The satisfiability and finite satisfiability problems for the two-variable guarded fragment of first-order logic with counting quantifiers, a database, and path-functional dependencies are both ExpTime-complete.

Satisfiability modulo theories and chiral heterotic string vacua with positive cosmological constant

open access: yesPhysics Letters B, 2021
We apply Boolean Satisfiability (SAT) and Satisfiability Modulo Theories (SMT) solvers in the context of finding chiral heterotic string models with positive cosmological constant from Z2×Z2 orbifolds.

SAT-based Explicit LTL Reasoning [PDF]

open access: yes, 2015
We present here a new explicit reasoning framework for linear temporal logic (LTL), which is built on top of propositional satisfiability (SAT) solving.
