. After discussing these properties, an integer programming approach is offered for solving them. The computational approach …

. It is shown how a simple generalization of the conventional branch-and-bound approach to integer programming makes it …

intractable because we have to solve nonlinear integer programming problems for which there exists no efficient algorithms. We … will show that these problems can now be solved by the state- of-the-art integer programming methodologies if we use …

-variance model can be solved exactly and fast by using the state-of-the-art integer programming approach. This implies that we can …
