## Problem 016 — rank:296

**Title:** Intracellular logistics

**Added binding assumptions (LaTeX):**

```latex
Stop ATP accounting at $\tau=T\wedge\tau_D\wedge\tau_L$ and define failure as the complement of $\{\tau_D\leq T,\tau_D<\tau_L\}$. Specify the tie convention and predictable local information available to policies. The infimum ranges over that same nonanticipating policy class. Low optimal-control regret is distinct from evidence that the biological transport policy is optimal.
