We study complexity and approximation of min weighted node coloring in planar, bipartite and split graphs. We show that this problem is NP-complete in planar graphs, even if they a...
The World Wide Web may be viewed as a graph each of whose vertices corresponds to a static HTML web page, and each of whose edges corresponds to a hyperlink from one web page to an...
The crossbar fabric is widely used as the interconnect of high-performance packet switches due to its low cost and scalability. There are two main variants of the crossbar fabric:...
Abstract Synchronising Graphs is a system of parallel graph transformation designed for modeling process interaction in a network environment. We propose a theory of context-free s...
High frequency digital LSIs usually consist of many subcircuits coupled with multi-conductor interconnects embedded in the substrate. They sometimes cause serious problems of the ...
