An Automata-Based Symbolic Approach for Verifying Programs on Relaxed Memory Models
This paper addresses the problem of verifying programs for the relaxed memory models implemented in modern processors. Specifically, it considers the TSO (Total Store Order) relax...

Improving NFA-Based Signature Matching Using Ordered Binary Decision Diagrams
Network intrusion detection systems (NIDS) make extensive use of regular expressions as attack signatures. Internally, NIDS represent and operate these signatures using finite au...

On Succinct Representations of Textured Surfaces by Weighted Finite Automata
: Generalized finite automata with weights for states and transitions have been successfully applied to image generation for more than a decade now. Bilevel images (black and whit...

A Family of NFAs Free of State Reductions
Merging states in finite automata is a main method of reducing the size of the representation of regular languages. The process has been extensively studied for deterministic fi...

Two-Way Finite Automata with a Write-Once Track
The basic finite automata model has been extended over the years with different acceptance modes (nondeterminism, alternation), new or improved devices (two-way heads, pebbles, ...

A note on emptiness for alternating finite automata with a one-letter alphabet
We present a new proof of PSPACE-hardness of the emptiness problem for alternating finite automata with a singleton alphabet. This result was shown by Holzer (1995) who used a pr...

On the Existence of Lookahead Delegators for NFA
We investigate deterministically simulating (i.e., solving the membership problem for) nondeterministic finite automata (NFA), relying solely on the NFA’s resources (states and...

An Optimal Construction of Finite Automata from Regular Expressions
We consider the construction of finite automata from their corresponding regular expressions by a series of digraph-transformations along the expression’s structure. Each interm...

Inapproximability of Nondeterministic State and Transition Complexity Assuming P=!NP
Abstract. Inapproximability results concerning minimization of nondeterministic finite automata relative to given deterministic finite automata were obtained only recently, modul...

Interconnected Automata and Linear Systems: A Theoretical Framework in Discrete-Time
This paper summarizes the definitions and several of the main results of an approach to hybrid systems, which combines finite automata and linear systems, developed by the author...
