Minsum ,-Sink Problem on Dynamic Flow Path Networks,k, and consider the problem of locating a set of . sinks on a dynamic flow path network with . vertices, where people are located, that minimizes the sum of the evacuation times of all evacuees. Our minsum model is more difficult to deal with than the minmax model, because the cost function is not m

Fully Leafed Induced Subtrees, We study the associated optimization problem, that consists in computing the maximal number of leaves, denoted by ., realized by an induced subtree with . vertices, for .. We begin by proving that the . problem is NP-complete in general. Then, we describe a nontrivial branch and bound algorithm tha
