title: Why does GlobalSearch return different solutions each run?
body: <p>When running the GlobalSearch solver on a nonlinear constrained optimization problem I have, I often get very different solutions each run. For the cases that I have an analytical solution, the numerical results are less dispersed than the non-analytical cases but are still different each run. It would be nice to get the same results at least for these analytical cases so that I know the optimization routine is working properly. Is there a good explanation of this in the Global Optimization Toolbox User Guide that I missed?</p>
  
  <p>Also, why does GlobalSearch use a different number of local solver runs each run?</p>
  
  <p>Thanks!</p>
