Infeasibility row

[Agostino]

Good morning,
I have a problem with my model. When I try to solve it, this is the
output of CPLEX:
"CPLEX 10.1.0: Infeasibility row 'cCPLEX 10.1.0: integer infeasible.
0 MIP simplex iterations
0 branch-and-bound nodes; no basis."
It does exist a way to show the row (or the number of the row) implied
in infeasibility?
Thank you so much
Agostino

It looks like CPLEX it trying to tell you the infeasibility row where it
states

CPLEX 10.1.0: Infeasibility row 'c

but then it is cut off by the next CPLEX message (which ought to go on the
following line). If you can't see an obvious way to fix this, send the
model and data and I'll see if I can reproduce the problem.

Dear all,

I wish to initialize the dual variables (or reduced costs) of the bound
constraints using AMPL for sending them to Ipopt. I have tried the suffixes
.rc, .dual, .dinit0 among others, and AMPL always complains saying that
these are not "assignable suffixes".

- How can I initialize them?
- Is there a complete list of "assignable" suffixes?

Thanks in advance!
Adela
