Table 2. Zero order of the Improvement of PC Algorithm based on CMI test.

1: Start with a complete undirected graph Inline graphic.
2: Repeat
3:  For each Inline graphic
4:   For each Inline graphic
5:    If X and Y are independent based on the measure of MI
6:     Remove the edge between X and Y from Inline graphic
7: The MIT score was utilized in the HC algorithm to construct Inline graphic.
