Abstract

Can a longer run over a small level set catch up with a shorter run sampling broadly? Public easy-mode Procgen logs offer a descriptive comparison, although their worker roles differ. Unrestricted-level online returns near twenty-five million training steps exceeded the unrestricted evaluation returns of fifty-million-step, two-hundred-level training in all sixteen game averages. The mean normalized contrast was 0.2531, with a working interval of 0.1322 to 0.3741. The analogous fifty-million-step contrast was 0.3415. These source-protocol differences caution against treating additional repeated exposure as an automatic replacement for breadth; they do not identify the causal benefit or computational price of level diversity.

Observational comparison of archived learning protocols. Source training-step counts are compared directly; wall time, total actor work, and fresh policy evaluation are unavailable.
