Subject: StackOverflowError while using Dijkstra from myPlugin
Print | Individual message | Show original | Report this message | Find messages by this author

Hi to all!
I try use Dijkstra from myPlugin, but get error:
{
  "exception" : "StackOverflowError",
  "stacktrace" : [ "java.util.LinkedList.addLast(LinkedList.java:181)",
"org.neo4j.graphalgo.impl.shortestpath.Util.constructAllPathsToNodeAsNodeLi nkedLists(Util.java:230)"
,
"org.neo4j.graphalgo.impl.shortestpath.Util.constructAllPathsToNodeAsNodeLi nkedLists(Util.java:209)"
,
...

}

I call dijkstra via follow script:

 Dijkstra<Double> pathFinder = new Dijkstra<Double> (0.0, nodeFrom, nodeTo,
 new RouterCostEvaluator(cost), new DoubleAdder(), new DoubleComparator(),
Direction.OUTGOING, drt );
 pathFinder.limitMaxCostToTraverse( maxCost );
 pathFinder.getPathsAsNodes();

Why?

pathFinder.limitMaxNodesToTraverse(100000);

- works good
pathFinder.limitMaxNodesToTraverse(1000000);

- get error

Can I use Dijkstra without "pathFinder.limitMaxNodesToTraverse(100000);" ?

Could you use the public Dijkstra implementation instead? I.e.
org.neo4j.graphalgo.impl.path.Dijkstra, accessible fom GraphAlgoFactory

Can this Dijkstra class may return some shortest paths?
The findSinglePath  method  return only one path. The findAllPaths method
working too long time...

And findSinglePath method is very hard (need more memory and CPU time)...
