When I use Nminimize to solve a nonlinear constrained problem, Mathematica changes my weak inequality constraint to a strong inequality (i.e. it changed F1>0 to F1>=0). How can I prevent it from doing this? Nminimize[{f[F1,F2....], {F1>0, F2>0, ....}}, {F1, F2, ....}]; This is the error I get (although it does print out an answer, it sets F1=0 and I don't want F1 to be zero): NMinimize::strong : Strong inequality has been changed to a weak inequality. Any help would be greatly appreciated. Thanks. -Janine
