| 2713 | * during the Fourier-Motzkin elimination. |
| 2714 | * Note that it is only useful to introduce lower bounds on "div" |
| 2715 | * if "bmap" already contains upper bounds on "div" as the newly |
| 2716 | * introduce lower bounds can then be combined with the pre-existing |
| 2717 | * upper bounds. Similarly for upper bounds. |
| 2718 | * We therefore first check if "bmap" contains any lower and/or upper bounds |
| 2719 | * on "div". |
| 2720 | * |
| 2721 | * It is interesting to note that the introduction of these constraints |
| 2722 | * can indeed lead to more accurate results, even when compared to |
| 2723 | * deriving constraints on the argument of "div" from constraints on "div". |
| 2724 | * Consider, for example, the set |
| 2725 | * |
| 2726 | * { [i,j,k] : 3 + i + 2j >= 0 and 2 * [(i+2j)/4] <= k } |
| 2727 | * |
| 2728 | * The second constraint can be rewritten as |
| 2729 | * |
| 2730 | * 2 * [(-i-2j+3)/4] + k >= 0 |
| 2731 | * |
| 2732 | * from which we can derive |
| 2733 | * |
| 2734 | * -i - 2j + 3 >= -2k |
| 2735 | * |
| 2736 | * or |
| 2737 | * |
| 2738 | * i + 2j <= 3 + 2k |
| 2739 | * |
| 2740 | * Combined with the first constraint, we obtain |
| 2741 | * |
| 2742 | * -3 <= 3 + 2k or k >= -3 |
| 2743 | * |
| 2744 | * If, on the other hand we derive a constraint on [(i+2j)/4] from |
| 2745 | * the first constraint, we obtain |
| 2746 | * |
| 2747 | * [(i + 2j)/4] >= [-3/4] = -1 |
| 2748 | * |
| 2749 | * Combining this constraint with the second constraint, we obtain |
| 2750 | * |
| 2751 | * k >= -2 |
