示例1: gb

// complete algorithm to compute a Groebner basis F
void gb( IntermediateBasis &F, int n) {
  int nextIndex = F.size();
  rearrangeBasis(F, -1);
  interreduction(F);
  Pairs B = makeList(F, n);
  //unsigned int countAddPoly = 0;
  //unsigned int numSPoly= 0;
  int interreductionCounter = 0;
  while (!B.empty()) {
    Pair pair = *(B.begin());
    B.erase(B.begin());
    if (isGoodPair(pair,F,B,n)) {
      //numSPoly++;
      BRP S = sPolynomial(pair,F,n);
      reduce(S,F);
      if ( ! S.isZero() ) {
        //countAddPoly++;
        F[nextIndex] = S;
        if(interreductionCounter == 5) {
          interreductionCounter = 0;
          interreduction(F);
          B = makeList(F, n);
        } else {
          interreductionCounter++;
          Pairs newList = makeNewPairs(nextIndex, F, n);
          B.insert(newList.begin(), newList.end());
        }
        nextIndex++;
      }
    }
  }
  interreduction(F);
  //cout << "we computed " << numSPoly << " S Polynomials and added " << countAddPoly << " of them to the intermediate basis." << endl;
