Genetic Algorithm optimization - using the -O3 flag
<p>Working on a problem that requires a GA.  I have all of that working and spent quite a bit of time trimming the fat and optimizing the code before resorting to compiler optimization.  Because the GA runs as a result of user input it has to find a solution within a reasonable period of time, otherwise the UI stalls and it just won't play well at all.  I got this binary GA solving a 27 variable problem in about 0.1s on an iPhone 3GS.</p>

<p>In order to achieve this level of performance the entire GA was coded in C, not Objective-C.</p>

<p>In a search for a further reduction of run time I was considering the idea of using the "-O3" optimization switch only for the solver module.  I tried it and it cut run time nearly in half.</p>

<p>Should I be concerned about any gotcha's by setting optimization to "-O3"?  Keep in mind that I am doing this at the file level and not for the entire project.</p>
