... Algorithm 6 (Lovasz). To test whether det(A) = 0 for the matrix A (with elements being polynomials) choose some field F (for example Zp for some large prime p) and randomly assign values to variables, and then check whether the determinant of a resulting matrix (with elements from F ) is equal to ze ...
