Subclaims¶
Reading the evidence codes
q is the design tier, i the impact, n the sample, and the kind with its r
the rigour judged within that kind: what each code means.
This claim: no standardized effect is recorded in observations/ for it yet, so no benchmark reading is possible.
q2 i? After 300 training iterations the PPO mechanism's cumulative expected return remained stable at 95.12 ± 1.23 (about 0.79 per step), while a random policy baseline yielded 12.3 ± 4.7 under the same evaluation conditions. → Zhu Z 2026

q2 · i? · causal · r1
Numerical simulation/evaluation result comparing the trained PPO policy against a uniform random-action baseline over the same 120-step episode length, aggregated across 30 independent evaluation runs (10 per random seed). The PPO policy's cumulative reward was 95.12 ± 1.23 (mean across 3 seeds) versus the random baseline's 12.3 ± 4.7; no effect size is printed for this comparison.
"a random policy baseline (uniform action sampling) yielded a cumulative reward of 12.3 ± 4.7 under the same evaluation conditions, confirming that the PPO-driven policy substantially outperforms chance"
