    • hasUseGlop

      public boolean hasUseGlop()
       If true runs Glop's presolver on the given instance prior to solving.
 Note that convergence criteria are still interpreted with respect to the
 original problem. Certificates may not be available if presolve detects
 infeasibility. Glop's presolver cannot apply to problems with quadratic
 objectives or problems with more than 2^31 variables or constraints. It's
 often beneficial to enable the presolver, especially on medium-sized
 problems. At some larger scales, the presolver can become a serial
 bottleneck.
      optional bool use_glop = 1;
      Specified by:
      hasUseGlop in interface PrimalDualHybridGradientParams.PresolveOptionsOrBuilder
      Returns:
      Whether the useGlop field is set.
