Exact Algorithms for Exact Satisfiability and Number of Perfect Matchings
We present exact algorithms with exponential running times for variants of n-element set cover problems, based on divide-and-conquer and on inclusion

General criteria for asymptotic and exponential stabilities of neural network models with unbounded delays
For a family of differential equations with infinite delay, we give sufficient conditions for the global asymptotic, and global exponential stability of an equilibrium point. Th...

Space Complexity vs. Query Complexity
Abstract. Combinatorial property testing deals with the following relaxation of decision problems: Given a fixed property and an input x, one wants to decide whether x satisfies th...

MAX3SAT is exponentially hard to approximate if NP has positive dimension
Under the hypothesis that NP has positive p-dimension, we prove that any approximation algorithm A for MAX3SAT must satisfy at least one of the following:

New updating criteria for conflict-based branching heuristics in DPLL algorithms for satisfiability
The paper is concerned with the computational evaluation and comparison of a new family of conflict-based branching heuristics for evolved DPLL Satisfiability solvers. Such a fami...
