Next, a special, highly efficient algorithm, the tree algorithm, is … WebNetwork Flow Problems • Network flow problems can be represented as “graphs”, i.e. a collection of nodes connected by arcs. • There are three types of nodes: – “Supply” or “Source” (less flow goes in than comes out) – “Demand” or “Sink” (more flow goes in than comes out) – “Transshipment” (inflow = outflow) We do not use multiple arcs within a network because we can combine those arcs into a single arc. To combine two arcs into a single arc, we add their capacities and their flow values, and assign those to the new arc: • Given any two nodes u and v, having two arcs from u to v with capacities c1(u,v) and c2(u,v) respectively is equivalent to considering only a single arc from u to v with a capacity equal to c1… slow cooker slimming world recipes
