Default Re: Quadratic programming

Any thoughts on R? I seem to be tweaking it and the program will not let me get my 1000 iterations. If I change the upper bound too low then either it gives me my iterations with a wrong answer (I submitted it and got the wrong answer), or it says that the matrix is not positive definite. It does not let me have an upper bound beyond about 1000. My threshold also has to be tights (about .01 or so, otherwise I get an answer but it is not correct). Is there a general way to deal with these issues when utilizing it practically? I have been using ipop in R.
