<br>
To see all the optimizer options, go to the base class in Doxygen:<br>
<br>
  <a href="http://www.itk.org/Doxygen/html/classitk_1_1SingleValuedNonLinearOptimizer.html" rel="noreferrer" target="_blank">http://www.itk.org/Doxygen/html/classitk_1_1SingleValuedNonLinearOptimizer.html</a><br>
<br>
Then, look at the inheritance diagram.  There are options like the<br>
OnePlusOneEvolutionaryOptimizer and ParticleSwarmOptimizer.<br>
<br>
Hope this helps,<br>
