NAME

   cbc - Cbc mixed integer programming solver

SYNOPSIS

   cbc [ options ] filename

DESCRIPTION

   This manual page documents briefly the cbc command.

   cbc  --  Cbc  (Coin-or  branch and cut) is an open-source mixed integer
   programming solver written in C++.

OPTIONS

   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

   -csv   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

INTERACTIVE MODE

   In interactive mode one command per line is expected (no leading -).

   ?      lists all available commands

   <command>?
          gives list of possibilities, if only one + explanation

   <command>??
          adds explanation, if only one fuller help

   <command>
          without value (where expected) gives current value

   <command> <value>
           sets value
