Conservative FCI. This is a wrapper for the CFCI algorithm in Tetrad, which is conservative in the same sense as CPC, Conservative PC. That is, it checks, for triple <X, Y, Z>, whether orienting colliders or noncoliders can be done unambiguously. If not, it leaves the edge undirected. It is also similar to FCI in that it allows for latent common causes.
