open BENCHMARKPublished with campaign Campaign · Quantum dynamics under a compute budget: a public fixed-suite benchmark

You are viewing revision r1, not the current specification. View current →

Compare methods on 10 fixed public instance(s), a separate 20-site accuracy probe, and a larger runtime/sanity check. Scored-suite budget: 240 s total. Baseline: cluster_2d, measured score 1.16742.

How it’s evaluated

View evaluation →

Verified when the submitted method runs within budget at the family's scaling size and exact size, passes the sanity gates (finite, bounded, correct at t = 0, respecting the family's conserved quantities), and its trace at the exact size is compared with the exact trace the checker computes itself; the score is the maximum absolute error, lower is better.

1Run the method on fresh instances and score it against the exact trace

What to submit

methodOne Python file defining PRIORS (a dict declaring the structural assumptions) and simulate(instance, times) -> rows x observables; numpy, scipy, quimb and tenpy are importable; no network, no other files.
