doe_lhs — MULTIVAR plan op

• データ種: なし → design(引数だけで決まる op —— 画像やデータの入力を取らない)
• 呼び出し: import fullseye as fs; fs.ledger.doe_lhs(n=10, factors=3, seed=0, maximin=0, centered=False) -> 'dict' (実装を直接呼ぶなら import doe; doe.doe_lhs(n=10, factors=3, seed=0, maximin=0, centered=False) -> 'dict'、台帳から引くなら opsmultivar.get("doe_lhs"))

使い方

Latin hypercube design (McKay, Beckman & Conover 1979) -> design.

Each factor’s range is cut into n equal strata and every stratum holds exactly one run, so each factor is sampled evenly however many factors there are (a random design of the same size leaves strata empty). Construction (McKay et al. 1979, section 2): for factor j draw an independent random permutation pi_j of 0..n-1 and put run i at u_ij = (pi_j(i) + U_ij) / n with U_ij ~ Uniform[0, 1) (centered=True uses the stratum mid-point, U = 1/2). Coded value = 2u - 1.

maximin=m (m >= 2) draws m independent hypercubes and keeps the one with the largest smallest inter-point distance (each candidate is still a Latin hypercube, so the stratum property is never traded away); 0 or 1 = one plain draw.

Parameters: n runs (2..1e6), factors (int or factor list, see module docstring), seed (int, reproducible), maximin (0..1000 candidates), centered.

Returns a design whose meta holds strata_ok (every factor has one point per stratum — the defining property, checked on the returned matrix) and min_distance (in the unit cube).
