Abstract
In this paper, the application of extraction principle for logic function minimization to multi-output case is studied. A defect in original algorithm in dealing with multi-output extrema is made up, and on this base, three kinds of less-than terms in different conditions are defined. In addition, three kinds of generalized definition of less-than terms are given, so as to find out more efficiently the covers with minimal number of terms and irredundant function outputs. This work makes the multi-output extraction principle closer to perfection. An algorithm based on the work is presented.
