I am using the latest versions (Neo4j 3.5.8, Algorithm library 3.5.8.0).
Given a simple two-node graph:
CREATE ({VID: 1})-[:EDGE {weight: 0.2}]->({VID: 2})
I'd like to run an SSSP algorithm and save the total cost of the paths to property SSSP.
SSSP
MATCH (startNode {VID: 1}), (endNode) CALL algo.shortestPath(startNode, endNode, 'weight', {write: true, writeProperty: 'SSSP', direction: 'OUTGOING'} ) YIELD nodeCount, totalCost, loadMillis, evalMillis, writeMillis RETURN endNode.VID, totalCost
The results are correct:
╒═════════════╤═══════════════════╕ │"endNode.VID"│"totalCost" │ ╞═════════════╪═══════════════════╡ │1 │-1.0 │ ├─────────────┼───────────────────┤ │2 │0.20000000298023224│ └─────────────┴───────────────────┘
But the propery contains the traversal level and not the total cost:
MATCH (n) RETURN n.VID, n.SSSP
╒═══════╤════════╕ │"n.VID"│"n.SSSP"│ ╞═══════╪════════╡ │1 │0 │ ├───────┼────────┤ │2 │1 │ └───────┴────────┘
Is there a way to write the total cost to the property?
