Given the following functional dependencies how would I compute the minimal cover:

A -> B, ABCD -> E, EF -> GH, ACDF -> EG

In the lectur

    According to me,In the above functional minimal dependencies ACDF -> G should also be included because when you take closure of each letter on left side and their combination none of them produce G without including F

    So it would be as follows:

    (A -> B, EF -> G , EF -> H , ACD -> E , ACDF -> G )
