Neo4j

I want to use neo4j to handle such a scenario: for example, I have a set of interrelated nodes,These nodes form a tree structure. These nodes have two types of labels A and B. How can I achieve that A labeled nodes can only appear at the end of the p...

I want to use the "label propagation algorithm" in APOC or other algorithm components to automatically calculate the labels of prediction nodes. Could you tell me how to realize this idea? Thank you.

Excuse me, What should I do if I want to change the label value or other attributes of some nodes?

In "match path=(u)-[*..]-(m) return path", I want to set or limit the label attributes of all nodes in the path, please tell me how to do it 。Thank you very much!

Hi! I want to find all closed circles in a directed connection diagram. That is, a node has a path back to itself through any node. Thank you very much!
