Hi Ankur,
I don't think you give enough information for me to give an explanation of what you report. A few thoughts:
- The speed on windows and Mac depend on the software but also the hardware. What sort of windows machine (type, number and speed of the cpu, amount of RAM) are you using? What about for your Mac? If the hardware is not comparable then comparing the speed between the two operating systems does not make sense.
- What optimization options were you using and on which problem. If you are using
poped_optim
then there are a series of optimization algorithms that are used. Some of those algorithms have random components, so unless you set the seed number before running the optimization you may get different results. The default options inpoped_optim
are set to get approximately the same answers when running the function with different seed numbers but for complicated design problems these default values may need to be changed.
Best regards,

Thanks for your suggestions. I used the seed number and it provides similar results across different machines.
