Direct methods have been proved to be effective and objective for solving superstructures. Two algorithms have been proposed to further improve the efficiency. The first was the same number of E's in all reflection groups. The second was a set of artificial E's in phase derivation to eliminate the effect from abnormal distribution of E values. The new algorithms have been incorporated into new version of SAPI.
