Dear sirs/ma' ams,
I'm planning to use Symphony on a series of mixed integer LPs, not all
integer variables are zeros and ones. Optimality of the objective function
is not very important, I just want a feasible solution.
I looked at the source code, in the file lp_branch.c .Above the routine:
branch_close_to_one_and_cheap()
,I found the comment:
/*****************************************************************************/
/* This works only for 0/1 problems!!! */
/*****************************************************************************/
The question is: why is that? Is it caused by the nature of the problem, or
the result of software shortcuts? Can the routine be generalized to work on
my problem?
I hope you can help. Goodbye, and thank you for your patience.
