This algorithm has optimizations that make it quicker than calling the Single Source Shortest Path algorithm for every pair of nodes in the graph. This algorithm is in the alpha tier.

For more information on algorithm tiers, see Algorithms. Some pairs of nodes might not be reachable between each other, so no shortest path exists between these pairs.

In this scenario, the algorithm will return Infinity value as a result between these pairs of nodes. Plain cypher does not support filtering Infinity values, so gds. The All Pairs Shortest Path algorithm is used in urban service system problems, such as the location of urban facilities or the distribution or delivery of goods. One example of this is determining the traffic load expected on different segments of a transportation grid. For more information, see Urban Operations Research.

All pairs shortest path is used as part of the REWIRE data center design algorithm that finds a network with maximum bandwidth and minimal latency.

Overview The all-pairs shortest path problem APSP finds the length of the shortest path for all source-destination pairs in a positively weighted graph.

We are faster than other approaches and achieve considerable performance as shown below. Benchmarks Performance obtained on a Pentium 4, data type single precision float. Vector means 4-way SSE. Performance obtained on a Pentium 4, data type short integer.
