Abstract

This paper introduce a novel method for maintaining consistency of cardinality constraints in context of dynamic constraint satisfaction. The presented method adopt sensitivity analysis for feasible and minimum cost flows underlying all cardinality constraints. Moreover, we extend a dynamic all-pairs shortest path algorithm to support weight changes, insertion and deletion of multiple edges and show how this algorithm can be used to maintain consistency of values with the modified constraint.
