Abstract/Notes |
In this paper, we develop a new preflow algorithm for the minimum
flow problem, called deficit scaling algorithm. This is a special implementation of
the generic preflow algorithm for the minimum flow problem developed by Ciurea
and Ciupal˘a earlier. The bottleneck operation in the generic preflow algorithm is
the number of noncancelling pulls. Using the scaling technique (i.e. selecting the
active nodes with sufficiently large deficits), we reduce the number of noncancelling
pulls to O(n2 log c) and obtain an O(nm + n2 log c) algorithm. |
