Creates a human-digestable representation of the PathType.
Creates a human-digestable representation of the PathType. To make it human readable, we need to convert the integers that show up in the path type into their string representations, using the provided dictionaries.
Creates a machine-parseable representation of the PathType.
Creates a machine-parseable representation of the PathType. This must match the ObjectParser[PathType] implementation in the PathTypeFactory. Edges types, node types, and whatever else, are encoded as integers.
Is this the last hop? This determines whether the walk gets sent to the companion for tracking statistics.
Given the hop number and information about the current vertex, pick an edge to follow.
Given the hop number and information about the current vertex, pick an edge to follow.
The EdgeExcluder is an object that uses some global or external information to determine if the walk is not allowed, generally because it's using an edge from the test data, or an edge that we're trying to learn.
It is advisable, if at all possible, to do whatever you can to avoid looping over all of the edges in this method. This is in the inner loop of the PathFollower, and so it will get run a _lot_. Even worse, the processing is distributed across threads by vertex, and if you loop over all of the edges, you make the amount of computation done by each thread more uneven, because vertices that have lots of edges tend to get more walks at them. So, really, try hard to avoid a loop over all of the edges. The cache parameter should be helpful for that.
How many iterations should we run if we want to be sure we complete the computation for this path type?
