Multi-configurational self-consistent field - Wikipedia
WebMulti-configurational self-consistent field (MCSCF) is a method in quantum chemistry used to generate qualitatively correct reference states of molecules in cases where … WebMCFMO = set to 1 to remove redundant orbital Lagrangian elements in FMO-MCSCF. Note that corresponding orbital rotations will still be optimised but not considered when … WebTo achieve quadratic convergence in the orbital optimization, PySCF implements a general second-order solver called the co-iterative augmented hessian (CIAH) method [9] [10]. This method can be invoked by decorating the SCF objects with the newton () method: mf = scf.RHF(mol).newton() More examples can be found in examples/scf/22-newton.py. … rods meatery
