Maybe this helps see attached file.

People here generally like users to post code as Maple code instead of images or PDF, so they can copy-paste it.

Can you add another missing parameters like:?

 If you want only a real part of function A:

with(Optimization):

NLPSolve(Re(A), x = -1000 .. 0, maximize);

#[6743.84638351141, [x = -5.17589535847115]]

NLPSolve(Re(A), x = 0 .. 1000, maximize);

#[6743.84638351141, [x = 5.17589535876615]]

Yes I have read  documentation and I was surprised myself only two examples. It should be at least one features for one example.

Can you add actual code so people can copy-paste easily?

@9009134 

Post the code (using the big green up-arrow in the MaplePrimes editor)

Here are  link that might be of interest.

I'm extract zip file to "C:\Program Files\Maple 2018"  and open Maple with administrator restrictions, then its works.

Thanks.

A have a Windows 8.1 64 bit, and Maple 2018 64 bit. Probably is issue related to import. I do not know what may be the reason?

Hello

Exectuted worksheet Handwritten Digit Recognition.mw and give me an error?

What can be the reason?

We cannot help you, really, unless you post your code!

If you found a bug please send to Submit Software Change Request.

On my 4 years  very cheap old laptop on Maple 2018(Windows),take  the first evaulation about 4 minutes and 34 second.
