Re: [amibroker] Problem removing OptimizerSetEngine("cmae");, AmiBroker Email List Archive

Ton,

1. 1GB of Ram

2. 61 optimization steps, the total number for exahustive optimization

3. It was happening almost immediately after hitting the optimize button, but just now I tried running one of the files that was making it crash and cannot get it to crash. Even stranger the first time I ran the file today it took 5.5 minutes to run the 61 steps, and now I just ran it in 42 seconds. I don't understand it.

It must have been a memory problem on my end, but this occurred on Friday, Saturday and Sunday, but it is not happening now. Plus the exception report included the line below regarding module CMAE.dll, but this was when I had removed the CMAE line and was attempting exhaustive optimization.

Hi James,

Can you please let me know the following. Just to avoid a wrong conclusion ...

1. Internal memory on your system ? GBytes ?

2. Number of steps with exhaustive optimization ? Is 60 steps the total number or the number for cmae ?

3. Does this happen immed after hitting the OPTIMIZE button or after several steps ? So after 60 steps ?

Regards, Ton.

There are only 60 steps and it crashes on the second one. I have been able to replicate it. Any code that I have this line:

OptimizerSetEngine ( "cmae" ); will crash after I change it to: // OptimizerSetEngine( "cmae");

If I delete the line altogether, it still crashes.

Hi - Exhaustive optimizer can crash if the opt has too many steps and it eventually runs out of memory. Does the crash happen well into the opt?

Has anyone else had a problem removing this line from their code:

OptimizerSetEngine ( "cmae" );

and then trying to run an exhaustive optimization? Every file of code I remove this from, I then can an exception error crash when I try to optimize. I am running XP pro and version 5.29.6.
