Maximum ﬂow problem • Excess: excess(v) = ∑ e:target(e)=v f(e)− ∑ e:source(e)=v f(e) • If f is a ﬂow, then excess(v) = 0, for all v ∈V \{s,t} • Value of a ﬂow: val(f) = excess(t) • Maximum ﬂow problem: max{val(f) |f is a ﬂow in G} • Can be seen as a linear programming problem. If ToVisit is implemented as letâs take an image to explain how above. ��h$�}�����Pyw !�V]�]��?�N8�P f, and let S be the set of all nodes reachable from s in Gf. Let’s take an image to explain how the above definition wants to say. There are k edge-disjoint paths from s to t if and only if the max flow value is k. Proof. A ow of f(v;w) units on edge (v;w) contributes cost c(v;w)f(v;w) to the objective function. 2 0 obj
