The paper describes improved techniques for factoring univariate polynomials over the integers. The authors modify the usual linear method for lifting modular polynomial factorizations so that efficient early factor detection can be performed. The new lifting method is universally faster than the cl
Cell decompositions are constructed for polynomials f (x) # Z p [x] of degree n, such that n< p, using O(n 2 ) cells. When f is square-free this yields a polynomialtime algorithm for counting and approximating roots in Z p . These results extend to give a polynomial-time algorithm in the bit model f
