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...
