Abstract

This paper gives a new deterministic algorithm for the dynamic Minimum Spanning Forest (MSF) problem in the EREW PRAM model, where the goal is to maintain a MSF of a weighted graph with n vertices and m edges while supporting edge insertions and deletions. We show that one can solve the dynamic MSF problem using O(n) processors and O(log n) worst-case update time, for a total of O(n log n) work. This improves on the work of Ferragina [IPPS 1995] which costs O(log n) worst-case update time and O(n2/3 log m n ) work.
