Partially Resolved: stochastic-programming created. We still need a tag wiki and adding the tag to a few old questions.
Proposal: create tag "stochastic-programming"
Reason:
It's an area of research.
There's over a hundred stochastic programming questions.
@MartinSleziak It seems to me that c-star-algebras is not really relevant here, as the author only mention them to give an idea of the type of book they're after.
Thanks for the response. I'll probably leave the further retagging of this question to users who are more familiar with this topic. (Although I have to say that what you wrote seems reasonable.)
