Abstract. We consider optimization problems on weighted graphs where vertex and edge weights are polynomial functions of a parameter ,~. We show.

Apr 22, 1992 � We consider optimization problems on weighted graphs where vertex and edge weights are polynomial functions of a parameter .

In this paper, we give a constructive proof of this observation and an efficient algorithm for calculating the list of shortest paths between two vertices in�...

Typically, FPT algorithms parameterized by treewidth are based on dynamic programming (DP) over a tree decomposition. Starting from the leaves of the tree�...

We explore if the known tight lower bounds parameterized by the width of the given tree decomposition remain valid if we parameterize by the size of the given.
