ons and 8 gradient evaluations. This is, not surprisingly, far fewer iterations than required for sampling; even fewer iterations would be used with less stringent user-specified convergence tolerances. The <code>alpha</code> value is for step size used. In the final state the change in parameters was roughly <span class="math inline">\(0.002\)</span> and the length of the gradient roughly 3e-05 (<span class="math inline">\(0.00003\)</span>).</p>
