## Problem 220 — rank:310

**Title:** Optimal epidemic control under uncertainty

**Added binding assumptions (LaTeX):**

```latex
Supply the full transition and observation kernels, initial state and nonanticipating policy class; bounded losses alone do not define the decision problem. The minimax gap is nonnegative by the elementary minimax inequality. Finite fully specified instances are computational decision problems, not automatically open conjectures. The residual target is informative, biologically grounded ambiguity classes, value-of-information bounds and robust evaluation without prescribing an action sequence.
