Description:
Writes branching priority data to a file.

• Task.readbranchpriorities Reads branching priority data from a file.
A.2.275
Task.writedata()
Task.writedata(filename)
Writes problem data to a file.
Arguments
filename : str
Data is written to the file filename if it is a nonempty string. Otherwise data is written
to the file specified by sparam.data file name.
Description:
See also
Writes problem data associated with the optimization task to a file in one of four formats:
LP:
A text based row oriented format. File extension .lp. See Appendix F.2.
MPS:
A text based column oriented format. File extension .mps. See Appendix F.1.
OPF:
A text based row oriented format. File extension .opf. Supports more problem types than
MPS and LP. See Appendix F.3.
TASK:
A MOSEK specific binary format for fast reading and writing. File extension .task.
By default the data file format is determined by the file name extension. This behaviour can be
overridden by setting the iparam.write data format parameter.
MOSEK is able to read and write files in a compressed format (gzip). To write in the compressed
format append the extension ”.gz”. E.g to write a gzip compressed MPS file use the extension
mps.gz.
Please note that MPS, LP and OPF files require all variables to have unique names. If a task
contains no names, it is possible to write the file with automaticly generated anonymous names
by setting the iparam.write generic names parameter to onoffkey.on.
Please note that if a general nonlinear function appears in the problem then such function cannot
be written to file and MOSEK will issue a warning.
• iparam.write data format Controls the output file format.
