摘要：
A new statistical approach to the configuration interaction problem is proposed. It will potentially reduce the size of CI vectors significantly and thus alleviate one of the main hindrances to doing very large CI calculations. This method will also provide us with statistical confidence limits on lower and upper bounds. These confidence bounds are qualitatively different from mathematically more rigorous lower bounds discussed elsewhere. The approach is discussed and possible algorithms presented.
