WebOct 8, 2012 · lets suppose in graph if we have (u,v)∈ E where w (u,v)=10 then if by adding a third vertex in between them like w (u,y)=1 and w (y,v)=3 now we find a path between u and v with weight 1+3=4<10. Now we will consider the second path as shortest which is (u,y,v) and will ignore the first one, this is relaxation.

Every edge u → v has a capacity c ( u → v) and a cost w ( u → v). A flow is defined as an assignment f: E → R such that: For every edge u → v, the flow sent along this edge is non-negative and does not exceed the capacity. graphql get all objects
