But it is very difficult to compute the number of non-negative matrix with fixed score row or column vectors, so to compute the number of tournament matrix with fixed score vector is also difficult.
According to different partitions of a set of input variables of the three-valued logic function, the compatibility relations of column (row) vectors of the three-valued logic function can be found.
