Generalizations of Matroids,e consider the problem of minimizing an arbitrary submodular function. This can be done in polynomial time with the .. For the important special case of symmetric submodular functions we mention a simple combinatorial algorithm.

Usually drilling machines can move in two directions: the table moves horizontally while the drilling arm moves vertically. Since both movements can
