<p>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.
</p>
<p>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.</p>
