Stored as a total energy in the convention of VarBench; quoted here as E/N (S.S), which is what the papers report (how the conversion works).

Every published energy

Grouped by what the number is. Ranking happens only inside the first group.

Strict variational upper bounds (4)

The record is the lowest eligible energy in this group, and only this group.

Flagged rows

A flag withholds the record and nothing else: the row stays listed, in rank order. Rules §10 is how a flag is lifted or upheld.

dof-mismatch — DMRG (bond dimension = 512), -0.5199011

Finding. Row stores dof = 100 on a 144-site instance. Same typo.

Coverage

No row here carries a publication year. Nothing has been added to this instance since the VarBench snapshot of 2024-10-22.
