We propose an algorithm that computes the length of a longest
path in a cactus graph. Our algorithm can easily be modified to output a
longest path as well or to solve the problem on cacti with edge or vertex
weights. The algorithm works on rooted cacti and assigns to each vertex
a two-number label, the first number being the desired parameter of the
subcactus rooted at that vertex. The algorithm applies the divide-and-conquer...
