These are questions asked by radaar

Does global optimization toolbox has randomization option it gives same value every time

Does globalsolve from global optimization toolbox thread safe or not

Does Maplesoft provide success percentage of this toolbox on benchmark functions?. I cannot see much options in the global solve command (from maple help page) other than population size etc. 

I would like to know whether a local optimizer is combined with the present global optimization toolbox?. I read that toolbox has differential evolution and surrogate optimization techniques etc. These methods guarantee near-optimal solutions and it is often recommended to use a local optimization technique in conjunction with global optimization techniques. 

Error, (in Optimization:-NLPSolve) the objective gradients at the initial point are too small

So this error indicates that the initial point is a local minimum or very very close to it right?
