How do you tune globalsearch parameters?

Hi Everyone
I have a trajectory optimization problem which I am attempting to solve using Globalsearch. With the default globalsearch options I am successfully able to optimize a 40 (20 *2 actuators) input trajectory.
However, I've now tried to increase the final time of my simulation and then increased my input variables to 60 (2 * 30) but globalsearch keeps returning local minima.
I saw that you can change the options for the globalsearch algorithm. Does anybody know which ones I should change? For example: will increasing my 'BasinRadiusFactor' to 0.4, make the algorithm search over a wider space? Or should I be changing the 'DistanceThresholdFactor'?
If anyone has a good tutorial or webinar on how to do this, that would be much appreciated.
Thanks in advance, Amir
