In the maximum flow problem, we have to find a flow path that can obtain the maximum possible flow rate. Figure 10 shows an animated example of determining the maximum flow of a network and determining the final flow value. Algorithms. Ford …
WebOct 25, 2024 · Graph theory provides a basis for identifying the spatial pattern of the road network in a primary level, thus proving to be a good method for pattern recognition of roads. Web(iii) β value exceeds 1 for a complicated network structure having more than one circuit. Alpha Index (α): One of the most useful measures of the connectivity of a network, particularly a fairly complex network, is the alpha index (α). The alpha index (α) for a non-planar graph may thus be defined as: α= actual circuit/ maximum circuits. Or
