Add example graph xml with 1000 vectors, 4000 edges, all objects
Bugfix vmMaxDistMinimumNorm
Minor refactoring
- implement relationaltest (V-MBR) in prune method;
- let getRKNNForObject return a Map<DBID, Double>
- small optimization: in filter, put pruned entries directly in correct ref set (point or node)
- other smaller refactoring&reformatting
- remove object insertion if nonexistent in graph case 'random'
Use example xml with 1000 nodes 4000 vertices, all objects; scenario with two results missing
