Network flow.
Dec 21, 2020 · The network flow problem can be conceptualized as a directed graph which abides by flow capacity and conservation constraints. The vertices in the graph are classified into origins (source X {\displaystyle X} ), destinations (sink O {\displaystyle O} ), and intermediate points and are collectively referred to as nodes ( N {\displaystyle N} ).

Figure 2 - An example of a raw flow for the network above. The flow has a value of 2. With a raw flow, we can have flows going both from \(v\) to \(w\) and flow going from \(w\) to \(v\). In a net flow formulation however, we only keep track of the difference between these two flows. Net flow is a function that satisfies the following conditions:
There are many types of problems that concern a network of conductors along which some sort of flow is observed. Examples of these include an irrigation network and a network of streets or freeways.
