The CCD-Max algorithm is a modification of the CCD algorithm (due to Thomas Richardson, see). It uses the PC-Max strategy to modify the CCD algorithm.
The algorithm is pointwise consistent for linear systems with Normal distributions, no latent variables and no correlated twoCycleErrors. It is similarly consistent for categorical variables with a Multinomial distribution if the true causal graph and the distribuiton satisfy the local Markov conditon--which is quite restrictive for categorical variables for cyclic systems.
