34 * @brief Find the order of variables which is optimal for GCD computation.
36 * Collects statistical information about the highest and lowest degrees
37 * of all variables that appear in two polynomials. Sorts the variables
38 * by minimum degree (lowest to highest). The information gathered by
39 * this function is used by GCD routines to find out the main variable
40 * for GCD computation.
