Bug?

I've built an influence diagram, and in it one of the decision nodes has two influences, but GeNIe only implements one of them, i.e. it does not make the decision conditional on one of the influences. In the attached, the "TCCOR at 1400" node doesn't seem to notice the influence of the "1400 forecas...

This doesn't actually give me what I want. What I would like is the expected value of the optimal decision at the decision node, when that decision is made using the information from the chance node. Do you know if there's an easy way to calculate that in GeNIe, without adding a prior decision node,...

Strange behavior

I have a few simple influence diagrams that GeNIe just doesn't seem to solve correctly. There are other ways to formulate the problem and get what looks like the right answer, but don't understand what is going wrong here. I'm attaching an example - the "Second Attempt" node seems to be correct (Val...

Automatic calculation of expected value of decision node

Does GeNIe have a way to automatically calculate the expected value of the first decision node in an influence diagram, if it is the child of an uncertainty node, or do I have to take the optimal expected values for each outcome of the uncertainty node and take their expectation by multiplying by th...
