A formal look at Info-Gap decision theory
by Associate Professor Moshe Sneidovich
Abstract: Info-Gap is a (very) young theory for decision-making under severe uncertainty. It presents itself as new and claims to be radically
different from all current theories for decision-making under uncertainty.
Its claim to fame is that it offers a probability-free approach to uncertainty.
We show that, in actual fact, not only that Info-Gap's generic model is not new, it is a simple instance of no other than . . . the most
famous model in decision-making under severe uncertainty, namely
Wald's  Maximin Model.
Furthermore, we show that Info-Gap is fundamentally flawed in that it does not deal with severe uncertainty, it simply and unceremoniously
