are a superfluous operations.
                 Key: SANDBOX-460
                 URL: https://issues.apache.org/jira/browse/SANDBOX-460
             Project: Commons Sandbox
          Issue Type: Improvement
          Components: Graph
    Affects Versions: Nightly Builds
            Reporter: Rodion Efremov
            Priority: Trivial
             Fix For: Nightly Builds


In the 
org.apache.commons.graph.shortestpath.DefaultShortestPathAlgorithmSelector 
there are such expressions as 'if (shortestDistancesForward.alreadyVisited( 
vertex))', which does nothing reasonable, but rather checks an invariant.
