Currently, the implementation automatically picks the inner parameters k and m for the Paterson-Stockmeyer evaluation based on the degree n of the polynomial to be evaluated. Each choice of these parameters gives a trade-off between the depth of the computation, the number of homomorphic multiplication, the number of rescale operations etc. Therefore, we should allow expert users to specify these parameters if desired.
