Description
This volume contains contributions to the 17th International workshop on Graph-Theoretic Concepts in Computer Science (WG ’91) held in Southern Bavaria in June 1991. These annual workshops are designed to bring together researchers using graph-theoretic methods to discuss new developments relating to or emerging from a diversity of application fields. The topics covered in this volume include: tree-related problems, graph grammarsand rewriting, complexity, computational geometry, parallel algorithms, vertex orderings, path-oriented algorithms, applications to VLSI, and disjoint cycle problems. Approximating treewidth, pathwidth, and minimum elimination tree height.- Monadic second-order evaluations on tree-decomposable graphs.- Optimal embedding of complete binary trees into lines and grids.- Graph rewriting systems and their application to network reliability analysis.- Nondeterministic control structures for graph rewriting systems.- A language for generic graph-transformations.- Attributed elementary programmed graph grammars.- The complexity of approximating the class Steiner tree problem.- On complexity of some chain and antichain partition problems.- Tight bounds for the rectangular art gallery problem.- Voronoi diagrams of moving points in the plane.- Using maximal independent sets to solve problems in parallel.- Fast parallel algorithms for coloring random graphs.- Optimal vertex ordering of a graph and its application to symmetry detection.- Edge separators for graphs of bounded genus with applications.- Line digraph iterations and the spread concept-with application to graph theory, fault tolerance, and routing.- A generalized encryption scheme based on random graphs.- Dynamic algorithms for shortest paths in planar graphs.- Complete problems for logspace involving lexicographic first paths in graphs.- A new upper bound on the complexity of the all pairs shortest path problem.- On the crossing number of the hypercube and the cube connected cycles.- Logic arrays for interval indicator functions.- On the broadcast time of the butterfly network.- On disjoint cycles.- Short disjoint cycles in cubic bridgeless graphs.
