Controls whether to avoid the AO->MO transformation of the two-electron integrals for the four-virtual case (<VV||VV>) by computing the corresponding terms in the AO basis. AO_BASIS = DISK algorithm reduces the memory requirements. It is, however, less efficient due to the extra I/O, so the default algorithm is preferred.

  • Type: string
