Difference Between Spdf And Dadf Best High Quality

Asking “which is best, SPDF or DADF?” is like asking “which is best, a recipe or a refrigerator?” They serve no common purpose.

The dAdf approach is a mathematical approximation for speed . It is not a different physics but an efficient algorithm, whereas the spdf approach (without fitting) is exact in the basis set limit but astronomically slower for large systems. difference between spdf and dadf best
