AVERT

Traversing Directed Eulerian Mazes (Extended Abstract),te-state automaton. Each of the algorithms puts one pebble in one of the exits of every vertex. These pebbles indicate an Eulerian cycle of the maze. The simple algorithm performs O(|V|·|E|) edge traversals, while the advanced one traverses every edge three times. Both algorithms use memory of size

On the Space and Access Complexity of Computation DAGs,ms. First, we present a unifying framework for proving lower bounds on the space complexity, which captures most of the bounds known in the literature for relevant CDAGs, previously proved through . arguments. Then, we expose a close relationship between the notions of space and access complexity, w

Split-Perfect Graphs: Characterizations and Algorithmic Use, induce a P. in H.We call a graph . if it is P.-isomorphic to a split graph (i.e. a graph being partitionable into a clique and a stable set). This paper characterizes the new class of split-perfect graphs using the concepts of homogeneous sets and p-connected graphs, and leads to a linear time reco

Networks with Small Stretch Number (Extended Abstract), graph in BID(.) can be characterized as follows: if some nodes have failed, as long as two nodes remain connected, the distance between these nodes in the faulty graph is at most . times the distance in the non-faulty graph. The smallest . such that . ∈ BID(.) is called . of .. In this paper we giv

Efficient Dispersion Algorithms for Geometric Intersection Graphs,vertices. We propose efficient algorithms solving the dispersion problem in interval graphs, circular-arc graphs, and trapezoid graphs. Graphs are supposed to be represented geometrically, rather than by their edge sets.

Optimizing Cost Flows by Modifying Arc Costs and Capacities,sed either to decrease the arc flow cost, or to increase the arc capacity, or both. The goal is to maximize the flow through the network while not exceeding bounds on the budget and on the total flow cost..The problems are NP-hard even on series-parallel graphs. We provide an approximation algorithm

Update Networks and Their Routing Strategies, and game-theoretic terminology as an underlying structure. For these networks we exhibit a simple routing procedure to update information throughout the nodes of the network. We also introduce an hierarchy for the class of all update networks and discuss the complexity of some natural problems.
