We study price-per-reward games on hybrid automata with strong resets. They generalise priced games previously studied and have applications in scheduling. We obtain decidability r...
Abstract. It it shown that the first-order theory of an automatic structure, whose Gaifman graph has bounded degree, is decidable in doubly exponential space (for injective automa...
We present a symbolic algorithm for strongly connected component decomposition. The algorithm performs (n log n) image and preimage computations in the worst case, where n is the n...
: A pushdown system is a graph G(P) of configurations of a pushdown automaton P. The model checking problem for a logic L is: given a pushdown automaton P and a formula L decide ...
We consider a permutation-based model for the gene assembly process in ciliates. We give a procedure to decide whether a given micronuclear molecules may be assembled by using onl...
