解决方案一 I am trying to perform a query to retrieve all paths between two nodes a and b in which all the paths there is a relationship property fulfilled. I have tried in many ways but I am not able to success. MATCH p=(o{value:"a"})-[r*]-(x{value:"b"}) where has(r.pr...

// maximum shortest path between two nodes MATCH (a:Character), (b:Character) WHERE id(a) > id(b) MATCH p=shortestPath((a)-[:INTERACTS*]-(b)) RETURN length(p) AS len, extract(x IN nodes(p) | x.name) AS path ORDER BY len DESC LIMIT 4 我们能看到网络中有许多长度为6的路径。
To find the shortest path between two nodes, Cypher offers a function called shortestPath, which can be used within a Cypher query to aplish this task. The basic syntax of using the shortestPath function in Cypher looks like this: MATCH (start:Node {name:"A"}), (end:Node {name:"B"...

Our newest pathfinding algorithm – the thirteenth addition to our Graph Data Science library – identifies the longest path between two nodes. It enables organizations to optimize complex scheduling, for example: Supply chain/resource allocation:If tasks on a critical path are completed late, project...
