DE coefficient C has huge effect on perfomance. Unfortunatelly not a single one (or equation) can work well for all examples. While C=0.8 is excellent for the one-obj ones (specially prob 9) and for the applications, this value makes the multi (two-obj) and more-than-3-obj perform really bad; for these ones, C=0.1 or even smaller is better
