## Problem 162 — rank:278

**Title:** Demographic-history identifiability

**Added binding assumptions (LaTeX):**

```latex
Specify whether additional genomes share a linked genealogy or are independent loci before translating total variation into sample size. For two simple laws, the minimum sum of testing errors is $1-\mathrm{TV}$; a positive distance alone does not provide a universal rate for composite, dependent experiments. Optimize separation over nuisance parameters and quotient relabelings, and treat the number and ages of added samples as part of the design.
