Note on representing attribute reduction and concepts in concept lattice using graphs
Mao (Soft Computing 21(24):7293–7311, 2017) claims to make contributions to the study of reduction in attributes in concept lattices by using graph theory. Some of her results could affect development of formal concept analysis; in particular, her three new algorithms for formal concept enumeration promise a lesser time complexity. Unfortunately, as we show, all the three algorithms are incorrect.
