cbc - Cbc mixed integer programming solver
[ options ] filename
This manual page documents briefly the cbc
-- Cbc (Coin-or branch and cut) is an open-source mixed integer
programming solver written in C++.
When no options are given cbc enters the interactive command line mode.
Otherwise the program enters a batch mode, for which a summary of options is
included below. Note that the order of options in the command line of the cbc
executable matter The command line of the cbc executable is parsed as if it
were in the interactive mode. The take-away is that if your using the command
line, and things aren't working as you think they should, try ordering the
commands in the sequence you'd use if you were interactive mode.
For a complete description, see /usr/share/doc/coinor-libcbc-doc.
- Read input from stdin instead of filename
- The option "-csv <filename>" causes cbc to
print one line of key output statics in commma separated format in a file
named <filename>. This option isn't currently included in the list
of commands given by the "?" command in interactive mode.
- -threads <num_threads>
- Run cbc in parallel using <num_threads> many CPUs
In interactive mode one command per line is expected (no leading -).
- lists all available commands
- gives list of possibilities, if only one + explanation
- adds explanation, if only one fuller help
- without value (where expected) gives current value
- <command> <value>
