\brief convert p == 0 into a solved form v == r, such that v has bounds [lo, oo) iff r has bounds [lo', oo) v has bounds (oo,hi] iff r has bounds (oo,hi'] The solved form allows the Grobner solver identify more bounds conflicts. A bad leading term can miss bounds conflicts. For example for x + y + z == 0 where x, y : [0, oo) and z : (oo,0] we prefer to solve z == -x - y instead of x == -z - y because the solution -z - y has neither an upper, nor a lower bound. The Grobner solver is augmented with a notion of a substitution that is applied before the solver is run. |
