DESCRIPTION

       Zimpl is a little  language  to  translate  the  mathematical  model  of  a  problem  into  a  linear  or
       (mixed-)integer mathematical program expressed in LPF or MPS file format which can be read by a LP or MIP
       solver.

       None  of  the  options  is  necessary.  All input files in zpl format that are given are concatenated and
       processed as if they are one big file. This makes is possible to combine different parts of  a  model  on
       the  command line. In this case the first filename given will be used as basename for the output files in
       absence of an -o option.

       The -t option is to select the output format.  mps can be read by every solver.  lpf is an CPLEX  format,
       but can also read by several solvers.  BE aware that for example Range-rows can not be expressed in lpf .
       If  you  want  to  inspected  the  output yourself, hum format is a variant of lpf with no name mangeling
       whatever, but unfortunately this violates several format restrictions, so no solver will  read  this  in.
       If rlp is specified the output is in lpf format, but rows and columns are randomly permuted.

OPTIONS

-b Enable bison(1) debugging output.

-D name=value
Sets the parameter name to the specified value. This is equivalent with having this line in the
Zimpl program: param name:=val .

-f Enable flex(1) debugging output.

-F filter
The output is piped through a filter. A %s in the string is replaced by the output filename. For
example: -F "gzip -c >%s.gz" would compress all the output files.

-h Show program help.

-l length
Sets the maximum length for variable names in LPF output files.

-m Write a CPLEX .mst Mip STart file.

-n cm|cn|cf
Select the format for the generation of constraint names. Can be either cm which will number them
1 ... n with a `c' in front. cn will use the name supplied in the subto statement and number them
1 ... n within the statement. cf will use the name given with the subto, then a 1 .. n number
like in cm and then append all the local variables from the forall statements.

-o outfile
Sets the base-name for the output files. Default is the name of the input file without extension.

-O Optimize the generated LP by doing some presolve analysis (experimental).

-P filter
The input is piped through a filter. A %s in the string is replaced by the input filename. For
example: -F "cpp -DWITH_C1 %s" would pass the input file through the C-preprocessor.

-r Write a CPLEX .ord branching order file.

-s seed
Set the random number generator seed.

-t lp|mps|hum|rlp|pip
Selects the output format. Can be either lp which is default, or mps , or hum , which is (only)
human readable, or rlp , which is randomly permuted, or pip , which means polynimial IP.

-v 0-5 Set the verbosity level. 0 is quiet, 1 is default, 2 is verbose, 3 is chatter, and 5 is debug.

-V Prints the version number.

DIAGNOSTICS

       The following diagnostics may be issued on stderr:

       101 Bad filename
              The name given with the -o option is either missing, a directory name, or starts with a dot.
       175 Illegal syntax for command line define -- ignored
              The  parameter  of  a  -D option was either not of the form name=value or the name was not a legal
              identifier.
       There are about a hundred other possible error messages, but these are either about the  contend  of  the
       input file, or system messages.
