wise, shift <span class="math">\(x_c\)</span> towards <span class="math">\(\bar{x}\)</span>, and repeat steps 2-5.</li>
</ol>
<p>Again, this is a highly simplified description of the
approach; for instance, we actually employ both the primal and dual
solutions to guide our judgements for shifting <span class="math">\(x_c\)</span> and
terminating.</p>
<p>This approach has proven surprisingly effective for many problems.
<em>However, as with many heuristic approaches, it
is not perfect.</em> It will sometimes
