[Couenne] Search direction

[ksismail]

Dear Pietro,

I got regularly a very bad solution when executing Couenne whith such
periodical messages:

in iteration .., slack too small, adjusting variable bound

and depending of the size problem,

EXIT: Search direction is becoming too small  or EXIT: Solved to Acceptable
Level.

Is something I can modify in the file mybonmin.opt to avoid such problem ?

Regards,

sismail
