# Cost_package

In the whole package “cost”, you can find :

casdi : MRCI program (MR-SDCI or DDCI),
dolo : localization of orbitals,
exsci also named casdiloc: selected MRCI (quasi linear MRCI),
noscf : to optimize orbitals (using MR-SCI and density matrices of the states, different spin multiplicity or spatial symmetry allowed),
faiano : to transform a basis set in an ANO form (sometimes useful for the localization)
etc…
