We propose an incremental algorithm for the problem of maintaining systems of difference constraints. As a difference from the unidirectional approach of Ramalingam et al., it employs bidirectional search, which is similar to that of Alpern et al., and has a bounded runtime complexity in the worst case in terms of the size of changes. The major challenge is how to update the solution efficiently after...
