## Problem 114 — rank:140

**Title:** Motor-control objective

**Added binding assumptions (LaTeX):**

```latex
Normalized nonnegative cost weights remove positive scaling but not additive constants, potential-based shaping or features indistinguishable on the reachable domain. Define the resulting cost-equivalence class and the admissible partially observed policy class. Optimal-control regret is an empirical hypothesis about behavior, not a consequence of fitting a cost retrospectively. Fix terminal cost normalization and the baseline task distribution.
