I will elaborate the meaning when I am free. You can check my update later.

Sep 22 answered Create sine function with random increase in phase Sep 21 answered Speeding up Position for finding the indices of a small number of integer elements in a large matrix Sep 19 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 :( Sep 18 comment obtaining random element of a set given by multiple inequalities @ybeltukov Very cool update! I will check about the tests. Sep 18 awarded Nice Answer Sep 18 revised obtaining random element of a set given by multiple inequalities added 1630 characters in body Sep 18 comment obtaining random element of a set given by multiple inequalities By the way you may also supply a measure using some statistic (PearsonChiSquareTest or KolmogorovSmirnovTest) to show how uniformity distributed your result really is? Sep 18 comment obtaining random element of a set given by multiple inequalities This is nice indeed! This is pretty general..Thx for finding it. +1 Sep 17 comment obtaining random element of a set given by multiple inequalities @ybeltukov That's why there was a "Result is not too bad!" In the concluding text. Hope you noticed!

If you make the pic bigger they come inside ;)....
