StateFittingScopeSplitALSConfigAttribute

enum cuquantum.bindings.cudensitymat.StateFittingScopeSplitALSConfigAttribute(value)

Configuration attributes for the variational ALS split-scope state- fitting configuration.DMRG-style sweep-to-sweep convergence. The cost function used for the relative tolerance is the squared residual norm C(k) = ||target - stateOut(k)||^2. Two-site (or multi-site) ALS sweeps re-split the joined site tensor via SVD; the truncation policy is controlled by an attached cudensitymatSVDConfig_t.
