      Potential fix for the *false positive* explore phase · 42987259
      Nguyen, Thien Minh authored
      
      
      The explore phase (locations as parameters) using soft-max to localize floating-point parameters.
      
      This worked in most of the cases unless the optimizer *accidentally* picked two identical location params at one layer and it created a local minimum.
      
      This can potentially terminate the explore phase early with less layers but some layers are combinations of multiple locations instead of just one location.
      
      Hence, the refine stage cannot find the solution when it fixes the location.

      Also, add options to specify lower and upper bounds for nlopt.
      
      The location params (during Explore) need to be in the (0.0, 1.0) range.
