<h3>But what is it?</h3>
<p>The program uses a simple genetic algorithm to evolve random two-wheeled shapes into cars over generations. Loosely
based on <a href="http://boxcar2d.com/">BoxCar2D</a>, but
written from scratch, only using the same physics engine (<a href="http://box2d.org/">box2d</a>).<br/>
seedrandom.js written by <a href="http://davidbau.com/">David Bau</a>. (thanks!)</p>
<h3>Controls</h3>
<table>
<tr>
<th>Save Population</th>
<td>Saves current population locally.</td>
</tr>
<tr>
<th>Restore Saved Population</th>
<td>Restore a previously saved population.</td>
</tr>
<tr>
<th>Suprise</th>
<td>Toggles drawing, makes the simulation faster.</td>
</tr>
<tr>
<th>New Population</th>
<td>Keeps the generated track and restarts the whole car population.</td>
</tr>
<tr>
<th>Create new world with seed</th>
<td>The same seed always creates the same track, so you can agree on a seed with your friends
and compete. :)
</td>
</tr>
<tr>
<th>Mutation rate</th>
<td>The chance that each gene in each individual will mutate to a random value when a new generation is
born.
</td>
</tr>
<tr>
<th>Mutation size</th>
<td>The range each gene can mutate into. Lower numbers mean the gene will have values closer to the
original.
</td>
</tr>
<tr>
<th>Elite clones</th>
<td>The top n cars that will be copied over to the next generation.</td>
</tr>
<tr>
<th>View top replay</th>
<td>Pause the current simulation and show the top performing car. Click a second time to resume
simulation.
</td>
</tr>
</table>
<h3>Graph</h3>
<table>
<tr>
<th>Red</th>
<td>Top score in each generation</td>
</tr>
<tr>
<th>Green</th>
<td>Average of the top 10 cars in each generation</td>
</tr>
<tr>
<th>Blue</th>
<td>Average of the entire generation</td>
</tr>
</table>
<h3>Genome</h3>
<p>
The genome consists of:
</p>
<ul>
<li>Shape (8 genes, 1 per vertex)</li>
<li>Wheel size (2 genes, 1 per wheel)</li>
<li>Wheel position (2 genes, 1 per wheel)</li>
<li>Wheel density (2 genes, 1 per wheel) darker wheels mean denser wheels</li>
<li>Chassis density (1 gene) darker body means denser chassis</li>
</ul>
<h3>Blurb</h3>
<p>This is not as deterministic as it should be, so your best car may not perform as well as it once did. The terrain
gets more complex with distance.<br/>
I'm not in the mood to deal with checking if all scripts have loaded before running, so refresh the page if things
seem whack.</p>
<h3>GitHub</h3>
<p>The code is now on a <a href="https://github.com/red42/HTML5_Genetic_Cars">GitHub repository</a>. Feel free to
contribute!</p>
<p>Originally written by <a href="http://rednuht.org">this guy</a>, now with contributions from patient people at GitHub.</p>
