Abstract: | We consider the problem of modifying the lengths of the edges of a graph at minimum cost such that a prespecified vertex becomes
a 1-maxian with respect to the new edge lengths. The inverse 1-maxian problem with edge length modification is shown to be
strongly
-hard and remains weakly
-hard even on series-parallel graphs. Moreover, a transformation of the inverse 1-maxian problem with edge length modification
on a tree to a minimum cost circulation problem is given which solves the original problem in
.
