<br>
I am solving large-scale MIP problems using the CBC solver and the AMPL
interface.<br>
<br>
For some problems, I know an integer feasible solution of good
"quality" and I would like CBC to use it as first incumbent solution
in the branch-and-bound tree.<br>
I think that the CBC option</span></font><font size=2 face="Courier New"><span

allows to do that.<br>
<br>
I use AMPL and I would like to know what is the AMPL command to use this
option?<br>
How can I tell CBC (with AMPL) which solution I would like to use as first
incumbent solution?<br>
<br>
Thanks very much,<br>
