title: Floyd–Rivest vs. Introselect algorithm performance
body: <p>Google couldn't help me so here it goes: which of the two selection algorithms, FloydRivest algorithm and Introselect, has better performance.</p>
  
  <p>I'm assuming It's FloydRivest algorithm, but want to be 100% sure. </p>
  
  <p>Also, if there exist even better algorithm for this purpose, I'd be glad to hear about them.</p>
