Transaction Science 0d59375329 wai-quantum: guided sampling, and the 4 × 4 space group to rounding ... VmcConfig::guide samples |ψ|² + guide·|ψ̄|² instead of |ψ|², |ψ̄| the chains' typical amplitude when the batch starts, and weights each sample back by |ψ|² over that; the error is then that of a weighted mean. Near a node of the network the local energy is a large number over a small one and |ψ|² visits too rarely for the variance to be measured; the floor visits. Zero, the default, samples |ψ|² as before: every pin and documented unguided figure is unchanged. On the trained 4 × 4 J1-J2 networks, enumerated: the ±0.1 network's guided variance came within 5 % of the exact one at every floor from 0.01 to 1, four seeds each (unguided seeds: 0.11 to 2.0 times it). The ±0.01 network's variance sits in two configurations of 12 870, which no 8000 samples visit reliably; guided seeds still gave 0.1 to 2.3 times it. Trained guided at 0.1 or 1, the same complex α = 1 space-group network, start and 600 steps reach the ground energy to 1.7e-12 and 1.2e-12 (unguided: 1.27e-3), variance below 4e-11. The sector holds 107 configurations up to symmetry against 288 parameters; the docs say so. Unprojected, the guide changes nothing (2.78e-2). Projected networks in the CLI and nqs_ground now sample with a guide of 0.1. A test holds guided estimates to enumeration on a projected 8-site ring (energy within 5σ, variance within 20 %) and bit-identity across thread counts.
