[Couenne] Regarding optimization issues with couenne

[Divyayan Dey]

Sir,
I am Divyayan Dey, an Electronics and Communication Engineering student
from India.
I am solving an optimization problem using couenne solver in Pyomo(the
problem being non-convex). I have a finite capacity to distribute among a
set of elements. However, with any initial guess [image: x0]  provided to
the solver, the optimized vector is messed up badly; e.g., with a capacity
of 1000 to distribute ,the optimized vector [image: x] gives
[897,1,1,1,1....] . With a capacity of 500, the vector [image: x] is
[397,1,1,...]. And when the optimization is done only in the convex portion
of the objective function, the initial guess [image: x0] is returned itself
showing no evaluations done. What could be a possible reason for this? I
can add the code if you would like to introspect.

Thanks. Regards,
Divyayan Dey
