The four-electron unlinked-cluster contribution to the correlation ener,g of a many-electron atom or molecule is derived for a CI wavefunction composed of a reference determinant and all double excitations from the reference determinant. The resulting formula is valid for small to moderate nambers o

The recently proposed stochastic diagonalization method is applied to the ab initio quantum chemistry configuration interaction problem. In this context it can be viewed as a multi-reference CI method with dynamic selection of important configurations. The method is compared with other methods and t

## Abstract Several modifications to the Davidson algorithm are systematically explored to establish their performance for an assortment of configuration interaction (CI) computations. The combination of a generalized Davidson method, a periodic twoβvector subspace collapse, and a blocked Davidson
Recent progress is reported in applications of iterative methods for calculations of molecular electronic continuum states. Vectors constructed in an appropriate Lanczos basis are seen to provide directly approximations to the interaction-prepared states of Fano and Cooper. Nondegenerate point-group
