[Coin-discuss] How to trace Cbc?

[Lou Hafer]

Spencer,

	Sorry to be the bearer of bad news, but it's likely time you started
digging into the documentation and code.

	There's a user's manual at http://www.coin-or.org/Cbc. Chapter 9 tells
you what you can get by boosting the log level.

	Additional information can be had.  You can start by #define'ing
CBC_DEBUG (see Makefile.solve or Makefile.test for an example, or edit the
files you're interested in tracing). Output is cryptic and undocumented, so
you'll need to scan the code to resolve some of the output. There are
additional defines to produce more detailed information on specific actions,
which you'll notice once you start looking.

	Last I looked, the default branching method was reliability branching,
as per Achterberg, Koch, Martin, OR Letters, v33, Jan. 2005.
