The graph orientation problem calls for orienting the edges of an undirected graph so as to
maximize the number of prespecified source-target vertex pairs that admit a directed path …

The graph orientation problem calls for orienting the edges of a graph so as to maximize the
number of pre-specified source–target vertex pairs that admit a directed path from the source …

Graph orientation is a fundamental problem in graph theory that has recently arisen in the
study of signaling-regulatory pathways in protein networks. Given a graph and a list of …

The graph orientation problem calls for orienting the edges of an undirected graph so as to

We consider a graph orientation problem arising in the study of biological networks. Given
an undirected graph and a list of ordered source-target pairs, the goal is to orient the graph …

The orientation of physical networks is a prime task in deciphering the signaling-regulatory
circuitry of the cell. One manifestation of this computational task is as a maximum graph …

Background We consider the following problem: Given an undirected network and a set of
sender–receiver pairs, direct all edges such that the maximum number of" signal flows" …

We introduce a graph-orientation problem arising in the study of biological networks. Given
an undirected graph and a list of ordered source–target vertex pairs, the goal is to orient the …

In a network orientation problem, one is given a mixed graph, consisting of directed and
undirected edges, and a set of source-target vertex pairs. The goal is to orient the undirected …

Background Network connectivity problems are abundant in computational biology
research, where graphs are used to represent a range of phenomena: from physical …
