[Cbc] How to get CBC-solution in AMPL format ?

[victor.zverovich at gmail.com]

Hi Vladimir,

If you have a problem in the .nl format you can solve it with the CBC
driver for AMPL and write a .sol file as follows:

  cbc <stub> -AMPL

where <stub> is the name of the .nl file without an extension.

HTH,
Victor
