MSDGW SEED

MSDGW_SEED = [integer]
Default: MSDGW_SEED = 2

Description: Seed for pseudo orbitals used by mixed stochastic-deterministic compression algorithm.^[1]

When set in combination with MSDGW_F, MSDGW_SEED changes the random phases of the stochastic orbitals determined by the compression algorithm. MSDGW_NXI stochastic orbitals $\lbrace |\xi_1\rangle, \cdots,|\xi_{N_\xi}\rangle \rbrace$ are determined from the original orbitals $\lbrace|\phi_1\rangle,\cdots,|\phi_N\rangle\rbrace$ by drawing $N_\xi \times N$ pseudo numbers $0\le \alpha_{i n}< 1$ and forming the linear combinations ${\displaystyle |\xi_i \rangle = \sum_{n=1}^{N} e^{i 2\pi \alpha_{in}}|\phi_n\rangle }$ .
