Tree automata and logic programs,paper..The tree languages accepted by PRA are (very close to) the minimal Herbrand models of definite sentences. Moreover, PRA are quite natural automata : they can be viewed as a natural extension of top-down tree automata. Thus, by means of PRA, one can make use of well-known techniques and ideas

An algorithm for two-layer channel routing,odel in which two wires are permitted to overlap for not more than a constant distance. This is an asymptotical improvement over the best known result ω=2d−1. The algorithm presented here has the following additional properties: (i) there are at most 6 pairs of over-lapping edges for any two wires p

On the relative complexity of subproblems of intractable problems,ct to p-many-one (Karp) reducibility. We also show, however, that not every problem has these properties. Furthermore, we discuss these completeness properties with respect to p-Turing (Cook) reducibility.

Tree automata and logic programs,of automata theory for studying definite sentences. As a proof of this fact, mainly using simulation techniques classical in automata theory, we give constructive proofs that :.The rest of the paper consists of two sections. In section 1 we shortly give the necessary definitions and in section 2 we intuitively explain the results mentioned above.

An algorithm for two-layer channel routing,roduced by it, (ii)it uses 6n contacts, where n is the number of nets to be connected, (iii)it can be implemented to run in time O(n). An extension of the algorithm to the multi-terminal problem is also discussed.
