[Symphony] Multiple Summation

[Ted Ralphs]

The objective you are trying to use is non-linear and SYMPHONY is a
linear solver. There are a number of codes in COIN that solve
non-linear problems. Check the list here:

and if you need more help, you could try coin-discuss. Hope this helps!

Cheers,

Ted
