Gap Detection for Genome-Scale Constraint-Based Models
Figure 1
(a) An illustration of a maximum flow problem on a graph. The numbers above the arcs are capacities, and we wish to maximize flow from the source to the sink ; equivalently, we wish to maximize flow along the artificial arc (, ) such that the flow at each node is balanced. (b) An example of a small maximum flow problem with a gap such that no flow along arc (, ) is possible.
