## Problem 271 — rank:185

**Title:** Distributed computation by cell populations

**Added binding assumptions (LaTeX):**

```latex
Close the population, intracellular, nutrient and signal-transport dynamics with boundary conditions and a full initial/noise law. Starting strain counts are positive and bounded below on the admissible ensemble. Finite-time computational reliability and long-term ecological persistence are different guarantees. Fix the readout time and whether spatially distributed outputs are pooled; changing that observation rule can change the computed Boolean function.
