We describe a class of simple transitive semiautomata that exhibit full exponential blow-up during deterministic simulation. For arbitrary semiautomata we show that it is PSPACE-c...
A mobile agent (robot), modeled as a finite automaton, has to visit all nodes of a regular graph. How does the memory size of the agent (the number of states of the automaton) inf...
Abstract. Several verification methods involve reasoning about multi-valued systems, in which an atomic proposition is interpreted at a state as a lattice element, rather than a B...
An emerging nanotechnology, quantum-dot cellular automata (QCA), has the potential for attractive features such as faster speed, smaller size, and lower power consumption than tra...
The problem of converting deterministic finite automata into (short) regular expressions is considered. It is known that the required expression size is 2(n) in the worst case for ...
