configuration interaction (ci)

What are the different types of CI?

There are several types of CI, each with varying levels of complexity and accuracy:
CIS (Configuration Interaction Singles): Includes single excitations from the reference configuration.
CISD (Configuration Interaction Singles and Doubles): Includes both single and double excitations.
CISDT (Configuration Interaction Singles, Doubles, and Triples): Includes single, double, and triple excitations.
Full CI: Includes all possible excitations, providing the most accurate results but at a high computational cost.
