# Bi-orthogonal Hartree-Fock

`ElemCo.BOHF`

— Modulebi-orthogonal Hartree-Fock method (using a similarity-transformed FciDump)

## Exported functions

`ElemCo.BOHF.bohf`

— Method`bohf(EC::ECInfo)`

Perform BO-HF using integrals from fcidump EC.fd.

`ElemCo.BOHF.bouhf`

— Method`bouhf(EC::ECInfo)`

Perform BO-UHF using integrals from fcidump EC.fd.

`ElemCo.BOHF.guess_boorb`

— Function`guess_boorb(EC::ECInfo, guess::Symbol, uhf=false)`

Calculate starting guess for BO-MO coefficients (left and right). Type of initial guess for MO coefficients is given by `guess`

. `uhf`

indicates whether the calculation is restricted or unrestricted.

See `ScfOptions.guess`

for possible values. (Note: `:SAD`

` is not possible here and will be replaced by identity matrix!)
