我试图弄清楚是否有一些基于关系总和获得两个节点之间的最短距离,给出了这个例子: neo4j图像示例
上图代码:
CREATE (some_point_1:Point {title:'Some Point 1'})
CREATE (some_point_2:Point {title:'Some Point 2'})
CREATE (some_point_3:Point {title:'Some Point 3'})
CREATE (some_point_4:Point {title:'Some Point 4'})
CREATE (some_point_5:Point {title:'Some Point 5'})
CREATE (some_point_6:Point {title:'Some Point 6'})
CREATE (some_point_1)-[:distance {value:100}]->(some_point_2)
CREATE (some_point_2)-[:distance {value:150}]->(some_point_4)
CREATE (some_point_1)-[:distance {value:200}]->(some_point_3)
CREATE (some_point_3)-[:distance {value:300}]->(some_point_4)
CREATE (some_point_2)-[:distance {value:500}]->(some_point_5)
CREATE (some_point_4)-[:distance {value:300}]->(some_point_5)
CREATE (some_point_5)-[:distance {value:300}]->(some_point_6)
CREATE (some_point_6)-[:distance {value:300}]->(some_point_1)
在此示例中,最短路径应为:some_point_1> some_point_2> some_point_4> some_point_5(100 + 150 + 300 = 550)
Cypher可以这样吗？
