comment Create sine function with random increase in phase
@Leo that's fine! I will elaborate the meaning when I am free. You can check my update later.

comment ParallelEvaluate for function minimization
@myaccount_ram Good that you came up with some code as a result your question is much concrete now. But I personally think in Mathematica all optimization routines are serial in nature by their design. It will be not at all easy if not completely impossible to adapt some of the gradient algorithms to use parallel function evaluation on multi-core architectures while building the run-time gradients or the Jacobians..We need some expert comment here! I am not one of them :(

By the way you may also supply a measure using some statistic (PearsonChiSquareTest or KolmogorovSmirnovTest) to show how uniformity distributed your result really is?

This is nice indeed! This is pretty general..Thx for finding it. +1

@ybeltukov That's why there was a "Result is not too bad!" In the concluding text. Hope you noticed!

@belisarius I guess it is some Graphics issue. If you make the pic bigger they come inside ;)....

comment ParallelEvaluate for function minimization
This kind of questions are too generic and shows little effort from your side. At least some toy example with code will help others to consider helping you right away. It can be a good question if you put some more relevant details and highlight what you have tried.
