Abstract

We consider the problem of maintaining minimum length paths in a directed graph G=(V,E) with n nodes while inserting new arcs. A data structure which supports the following operations is presented: an add operation, which inserts an arc in the digraph, and a minpath operation, which returns a minimal length path between a pair of nodes. The data structure supports each minpath operation in O(k) worst case time, where k
