Figure 26.1 (a) A flow network G=(V, E) for the Lucky Puck Company's trucking problem.
The Vancouver factory is the sources, and the Winnipeg warehouse is the sink f. The company ships
pucks through intermediate cities, but only c(u, v) crates per day can go from city u to city v. Each
edge is labeled with its capacity. (b) A flow f in G with value || = 19. Each edge (u, v) is labeled
by f(u, v)/c(u, v). The slash notation merely separates the flow and capacity; it does not indicate
division.
Transcribed Image Text:Problem 1. In Lecture 17, page 2, Figure 26.1(b), determine the flow across the cut
({s, V2, V₁}, {V₁, V3, t}) and determine the capacity of this cut.
