LISTb: a Better Direct Approach to LIST.

Following our recent paper on linear-expansion shooting techniques (LIST) [Wang, Y. A.; Yam, C. Y.; Chen, Y. K.; Chen, G. H. J. Chem. Phys.2011, 134, 241103], in which the direct approach (LISTd) and the indirect approach (LISTi) were proposed to accelerate the self-consistent field convergence, we discovered a highly simple solution to cure the linear-dependence problem of LISTd. The resultant method, LISTb, is a better direct approach to LIST and muscles similar performances to existing LIST methods. More promisingly, LISTb even outshines the best LIST method, LISTi, for systems involving transition-metal atoms.
