A core of a graph G is a path P in G that is central with respect to the property to path P. This paper presents efficient algorithms for finding a core of a tree with Ε½ . a specified length. The sequential algorithm runs in O n log n time, where n is the Ε½ 2 . Ε½. size of the tree. The parallel alg

A ''book-embedding'' of a graph G comprises embedding the graph's nodes along the spine of a book and embedding the edges on the pages so that the edges embedded on the same page do not intersect. This is also referred to as the page model. The ''pagenumber'' of a graph is the thickness of the small
In a rectangular grid, given two sets of nodes, S S sources and T T sinks , of size 2 Ε½ . each, the disjoint paths DP problem is to connect as many nodes in S S to the Ε½ nodes in T T using a set of ''disjoint'' paths. Both edge-disjoint and Β¨ertex-disjoint . cases are considered in this paper. Note
