WebFeb 28, 2024 · Graph path order refers to the order of data in the output path. The output path order always starts at the non-recursive part of the pattern followed by the nodes/edges that appear in the recursive part. The order in which the graph is traversed during query optimization/execution has nothing to do with the order printed in the output. WebJul 7, 2024 · 4.4: Euler Paths and Circuits. Investigate!

WebA path in a graph G is a subgraph of G that is a path graph (West 2000, p. 20). The length of a path is the number of edges it contains.
