[Couenne] memory problem

[Pietro Belotti]

Dear Ercan,

you can specify a limit for the maximum running time (option  
time_limit in couenne.opt) and for number of branch-and-bound nodes  
(option node_limit), but not for the maximum memory allocation.  
Unfortunately, the memory allocation depends highly depends on the  
number of nodes, and cannot be limited without affecting the  
performance.

Pietro
