<br><font size=2 face="sans-serif">Brady,</font>
<br>
<br><font size=2 face="sans-serif">I think CBC is now robust enough to
go into production so I hope to get the library to version 1.0 by INFORMS.
At present it is at 0.99!</font>
<br>
<br><font size=2 face="sans-serif">I have also created a stand alone CBC
executable which shares code with my stand alone CLP executable and
this is what people should use. It is intended to give good performance
with no options but there are many options. It is intended to give
hints in the same way as CLP although the explanations need more work.
Individual cuts may be switched on or off and you can also switch
on all (well most) cuts at root, in tree or let the code decide.</font>
<br>
<br><font size=2 face="sans-serif">To make it more useful there is also
a savesolution command which saves the solution to file in a very simple
format which can be used by other programs. The solution command
from clp is also there to print solutions.</font>
<br>
<br><font size=2 face="sans-serif">To obtain this executable (solve) use
"make solve" in the Cbc directory. I will be working on
this to make it better so any suggestions are welcome.</font>

<br><font size=2><tt>Is there a general CBC-based solver that can be easily
used without coding?<br>
<br>
I am doing some work on predicting time to solve and separate work on<br>
tuning parameters and would like to work with a general CBC solver.<br>
<br>
I know that CBC is intended primarily as a library, but I believe we<br>
should also have one or more general solvers clearly indicated for<br>
people who don't need/want to code their own. I thought there was
one,<br>
but it wasn't obvious to me as I looked through the files.<br>
<br>
Thanks,<br>
<br>
Brady<br>
