Hi, i need to minimize a quadratic function with boundary condidtions and one equality condition. In order to do that i converted the equality constraint into 2 inequality constaints
You can't do that with constrOptim. constrOptim requires the interior of the feasible region be non-empty. As it says, the starting value must be in the interior of the feasible region, which you didn't do. -thomas Thomas Lumley Assoc.
