Using the generator of UQBPs a class of small size problems was created. All test problems in this category have linear
coefficients in [ -100,100] and quadratic coefficients in [ -200,200].
The purpose of these 5400 test problems is to analyze how the number of variables (ranging from
20 to 100), density (ranging from 10% to 100%) and diagonal dominance influence the result
of a heuristic method.
The number of variables being ''small'' gives a more accurate analysis by the better chance that the best
known solution is in fact the optimum.
