#5 closed defect (fixed)

Returning infeasible takes a long time.

The problem is infeasible, it takes Clp a long time (more than 3 hours) to return that. I have tested the same problem on other solvers, cplex returned infeasible in 10 seconds and glpsol took 30 seconds to return the same.

I'm trying to clean up the old Clp tickets. Could you check that the ticket you submitted (#5) is still valid against the latest stable version (stable/1.5)?

Thanks, --Laci

  • Owner changed from somebody to forrest
  • Status changed from new to assigned

Still seems to take a long time. I will look at it.

I have tested this problem again, the times are better now:

  • clp (trunk/20080122), 115 s
  • glpsol (4.25), 57 s

This is on the same slow laptop.
