Efficient algorithms for finding minimum spanning forests of hierarchically defined graphs,is graph model. We solve decision problems pertaining to minimum spanning forests in almost linear time in the length of the hierarchical description, query problems in time linear in the depth of the hierarchy and we construct minimum spanning forests in space linear in the length of the hierarchical description.

Abstract interpretation of denotational definitions,or flow chart languages, but this paper extends the applicability of the idea to a wide class of languages that have a denotational semantics. The main idea is to study a denotational metalanguage with two kinds of types: one kind describes compile-time entities and another describes run-time entiti

Ions and local definitions in logic programming,. collections of clauses), and discuss derivability from these theories. In particular, they use amalgamation in order to give a solution to the .. In this paper we reconsider this locality of definition problem, and present a new approach for solving it, whithout calling upon language and metalangu

Polynomial time algorithms for finding integer relations among real numbers,there is no such integer relation with ‖m‖≦2.. One such algorithm halts after at most O(n.(k+n)) arithmetic operations using real numbers. It finds an integer relation that is no more than .times longer than the length of the shortest relation for x. Given a rational input x∈ℚ. this algorithm halts

Speeding up random access machines by few processors,. These machines work on integer inputs. It is shown that, in contrast to bit orientated models as Turing machines or log-cost RAMs, one can in many cases speed up RAMs by PRAMs with few processors. More specifically, a RAM without indirect addressing can be uniformly sped up by a PRAM with q proces

Efficient algorithms for finding minimum spanning forests of hierarchically defined graphs,ry large graphs. The model is motivated by applications in the design of VLSI circuits..We show how to efficiently find minimum spanning forests in this graph model. We solve decision problems pertaining to minimum spanning forests in almost linear time in the length of the hierarchical description,
