<p>One of the keys of the refactoring I did for serialization is that I attempted to keep the interfaces using references, and not pointers, for the sake of simplicity. i.e.</p>
<pre><code>RMSPROP(DecomposableFunctionType* function,
const double lr = 0.01,
const double alpha = 0.99,
const double eps = 1e-8) :
function(&function),
lr(lr),
alpha(alpha),
eps(eps)
</code></pre>
<p>I guess this would make the call to <code>new OptimizerType<></code> take <code>*this</code> instead of <code>this</code>.</p>
