Numerical Integration

ADF uses the unique Te Velde - Baerends numerical integration scheme, in which the grid is automatically adapted to the available basis functions and to the number of significant digits demanded by the user through a single input parameter. It is straightforward to do very accurate integrations with far fewer points than in less highly developed schemes. For some more details see also numerical integration details.
