<p>This example admittedly is a bit simplistic. With a bit of careful
arrangement, it is possible to rewrite this model so that the <span class="math">\(n\)</span>
equality constraints can be combined into a single vector constraint,
which in turn would require only a single vector dual variable. <a class="footnote-reference" href="#id4" id="id1">[3]</a>
For a more complex example that is not amenable to such a
simplification, see the file</p>
