The computational results on problems with up to 2750 variables strongly confirm our hypothesis that a combination of problem preprocessing, cutting planes, and clever branch-and-bound techniques ...

Operations Research, Vol. 33, No. 4 (Jul. - Aug., 1985), pp. 803-819 (17 pages) We present methods that are useful in solving some large scale hierarchical planning models involving 0-1 variables.

Key fact When solving simultaneous equations with a linear and quadratic equation, there will usually be two pairs of answers. y = x + 3 y = x 2 + 3 x ...
