    <description descriptionType="Abstract">&lt;p&gt;Geometrical algorithms have been the main subject of research in the field of real time sound rendering. These algorithms&lt;br&gt;
are variants of the image source and ray tracing algorithms, enhanced with improvements that speed up substantially their&lt;br&gt;
performance. The fundamental concepts behind the improvements achieved up to now was the reduction of the processed&lt;br&gt;
information and the acceleration of the actual processing. In this paper, we show how altering the traversal method affects&lt;br&gt;
significantly the algorithm&amp;rsquo;s performance. These optimizations alter its behavior, providing better results for real time purposes.&lt;br&gt;
We separate the techniques into three major categories and we propose a stochastic Monte Carlo algorithm which involves&lt;br&gt;
optimizations based on prioritization.&lt;/p&gt;</description>
