<p>can you also modify the other ann optimizer classes?</p>

<p>No problem</p>

<blockquote>
<p>I attempted to keep the interfaces using references, and not pointers</p>
</blockquote>

<p>Nice suggestion, but I think what you mean is</p>

<pre><code>RMSPROP(DecomposableFunctionType&amp; function, //reference, not pointer
          const double lr = 0.01,
          const double alpha = 0.99,
          const double eps = 1e-8) :
      function(&amp;function),
      lr(lr),
      alpha(alpha),
      eps(eps)
</code></pre>

<p>Thanks for closing replicated issue</p>
