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 :(

@ybeltukov Very cool update! I will check about the tests.

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.

comment Quadratic programming problem
Off topic but hope you agree MMA is not really updating its optimization capabilities over the last 5-8 years or even more and falling seriously behind as a multipurpose optimization suite. The breakthroughs in algorithms and new class of problems are hardly tractable (e.g using SuperFunctions like FindMinimum ) out of the box. SQP is one such major example. Anything interesting to expect in this direction of making FindMinimum more powerful and compatible to new age demands...?
