Abstract
The paper describes methods for solving very large overdetermined algebraic polynomial systems on an example that appears from a classification of all integrable 3-dimensional scalar discrete quasilinear equations Q 3=0 on an elementary cubic cell of the lattice ℤ3. The overdetermined polynomial algebraic system that has to be solved is far too large to be formulated. A “probing” technique, which replaces independent variables by random integers or zero, allows to formulate subsets of this system.
An automatic alteration of equation formulating steps and equation solving steps leads to an iteration process that solves the computational problem.
