Description

Is the current implementation of FCI algorithm complete according to [1]? The current version doesn't seem to include rules R5-R10 described in [1].

Reference:
[1] Zhang, Jiji. "On the completeness of orientation rules for causal discovery in the presence of latent confounders and selection bias." Artificial Intelligence 172.16-17 (2008): 1873-1896.

Research direction

Start by locating the current FCI implementation and comparing its orientation rules with R5–R10 in Zhang's 2008 paper, cited as reference [1]. Done means determining whether those rules are missing and, if so, updating the implementation with tests that demonstrate the expected orientations.
