Hi Khris, If all your variables are binary then you may want to check CPLEX and/or Gurobi (both provide a free academic license). http://www-01.ibm.com/software/integration/optimization/cplex-optimizer/ http://www.gurobi.com/products/additional-products-using-gurobi/r
The algorithms that CPLEX and Gurobi use for quadratic programming are designed to work with convex objective functions, with the one exception when all variables are binary. In that case CPLEX and Gurobi apply some transformation that in certain cases will allow you to solve binary quadratic optimization problems.
