neo4j shortest path with common relation property

发布于 2020-11-29 07:22:33

As the picture below shows we have nodes with relations but with different properties. how can I find shortest path between node A and node E with condition that relations in the path should have common property? for example here it only should give THE PATH with property "a" from node A to node B because a here is common.

Edit I want to find shortest path between node a and e based on available relations between a and next node (here relation properties are a, b and c) how can I find shortest path between a and e in which relations property is same(here property a) for example it should return only the path with property a (and the path would be a>b>d>e)

I found the answer and the answer was:

Match (a:node)-[r1]->()
with collect(r1.property) as m
MATCH p=shortestPath( (a:node)-[:r1*]->(e:node) ) 

AND ALL(x in relationships(p) WHERE x.propery in m)
RETURN p

Mamba is a new state space model architecture showing promising performance on information-dense data such as language modeling, where previous subquadratic models fall short of Transformers. It is based on the line of progress on structured state space models, with an efficient hardware-aware design and implementation in the spirit of FlashAttention.
