(LaTeX) Abstract:
We deal with the problem of maintaining the heaviest paths
in a DAG under edge insertion and deletion.
Michel and Van Hentenryck~\cite{Michel} designed algorithms for
this problem which work on DAGs with strictly positive edge
weights. They handle edges of zero or negative weight by
replacing each of them by (potentially many) edges with
positive weights. In this paper we show an alternative
solution, which has the same complexity and handles arbitrary
edge weights without graph transformations. For the case in which
all edge weights are integers, we show a second algorithm
which is asymptotically faster.
