LaFA: lookahead finite automata for scalable regular expression detection
Although Regular Expressions (RegExes) have been widely used in network security applications, their inherent complexity often limits the total number of RegExes that can be detec...

On polynomial cases of the unichain classification problem for Markov Decision Processes
The unichain classification problem detects whether a finite state and action MDP is unichain under all deterministic policies. This problem is NP-hard [11]. This paper provides p...

A variational description of the ground state structure in random satisfiability problems
A variational approach to finite connectivity spin-glass-like models is developed and applied to describe the structure of optimal solutions in random satisfiability problems. Our ...

Antichains: A New Algorithm for Checking Universality of Finite Automata
We propose and evaluate a new algorithm for checking the universality of nondeterministic finite automata. In contrast to the standard algorithm, which uses the subset construction...

Optimal Strategies in Perfect-Information Stochastic Games with Tail Winning Conditions
We prove that optimal strategies exist in perfect-information stochastic games with finitely many states and actions and tail winning conditions.
