[Bonmin] Bonmin memory problems in neos

[Diogo André Alagador]

Dear all,

 

I have a mixed-integer, nonlinear problem o solve with Bonmin. The problem
has to be applied to a big data set and therefore memory problems occurred
when I uploaded it to bonmin in neos facility.

The following message appeared:

 

> Error: Error at _cmdno 4 executing "solve" command

> Error: (file amplin, line 9181, offset 8138628):

> Error:

> processing commands.

> Error:     Too much memory used -- 3207740613 bytes; couldn't get 32800
more.

> Error (512) in /opt/ampl/ampl -R amplin

> Error:

 

 

It seems that I can change branch and bound settings but I don’t know how to
do it in order not to lose optimality.

Can anyone help me in this task.

 

Thanks in advance,

Greetings,

Diogo André Alagador
