D.4.18.12 getSmallest
Procedure from library normal.lib (see normal_lib).
- Usage:
- getSmallest(J); J is an ideal.
- Return:
- the generator of J of smallest degree. If there are more than one, it
chooses the one with smallest number of monomials.
- Note:
- It looks only at the generator of J, not at all the polynomials in
the ideal.
It is intended maninly to compute a good universal denominator in the
normalization algorithms.
Example:
| | LIB "normal.lib";
printlevel = printlevel+1;
ring s = 0,(x,y),dp;
ideal J = x3-y, y5, x2-y2+1;
getSmallest(J);
==> x2-y2+1
printlevel = printlevel-1;
