Non-negative quadratic maximization
First, note that the condition that $A$ be positive semidefinite (PSD) doesn't buy you anything. Replacing $A$ by $A+kI$ changes the objective value of any feasible solution by $k$, so if we could so …

Software for rigorous optimization of real polynomials
I see Gloptipoly has already been mentioned. This is an implementation of the general sum-of-squares/Positivstellensatz methods which allow one to relax polynomial problems into convex optimization p …
