DiscreteValue.getStringVal throws ArgumentOutOfBoundsException about burlap HOT 5 CLOSED

The discrete value object creates an array with various values that are set. These values might just be proxies for integers themselves, but the index into the array of values must still be positive, because it doesn't know that they're just a sequence of ints.

Alternatively, if you just want a very large number of integers (like your -5000 to +5000 example), you should use the IntValue type instead of the DiscreteValue type.

Thanks! INT type values was what I really needed.

Tangentially related, the MDP I am testing has an agent that moves stochastically on this integer line, with probabilities based on the actions taken. You could think about it like a monetary account balance that changes over time. Is there something built into Burlap that will graphically visualize this? I didn't find anything obvious, but I did notice that you provide a GraphDefinedDomain. My current thought is to take the data written to file from policy.evaluateBehavior.writeToFile and graph it externally.

Hmm probably not. Each visualizer is pretty specific to its domain so I'm not sure if there is something that can be easily co-opted to a 1D attribute visualizer. GraphDefinedDomain is also currently the only domain lacking a visualizer because I haven't yet decided what the best way to visualize arbitrary graphs is (graph visualization is effectively a research topic itself with many approaches).

It probably wouldn't be difficult for you to write your own if it's just a 1D visualization, but dumping to a file and using external graph tools would surely work as well.

That makes sense. Thanks again.
