title: Obtain solutions in Gekko by slightly relaxing constraints
body: <p>I have a modified version of the <a href="http://apmonitor.com/me575/index.php/Main/SpringDesign" rel="nofollow noreferrer">spring optimization Gekko model</a>.</p>
  <p>Is there a way to slightly relax constraints so that the solver can still give me solutions even if they start falling out of the range of my constraints?</p>
  <p>I'm aware of RTOL, but is there a way of specifying tolerances for individual equations?</p>
