How to Use

The program hardly has any user interface. Once you have compiled executable files, cdd, cddf+ and cddr+ (see Section 6 for cdd, Section 7 for cdd+), and once you create an input file, say, test.ine, you have basically two ways to run the program. The simplest way is just to run cdd/cdd+ with

  % cdd test.ine

or

  % cddf+ test.ine

or, if you want to compute with rational (exact arithmetic)

  % cddr+ test.ine

Then the program will open necessary output files with default file names as shown in Table 1 and output the requested results.

Table 1: Default extensions for output files

	Input File Format
options	H-format (*.ine)	V-format (*.ext)
conversion	*.ext	*.ine
incidence	*.ecd	*.icd
input_incidence	*.iad	*.ead
adjacency	*.ead	*.iad
input_adjacency	*.iad	*.ead
maximize/minimize	*.lps	non applicable
facet_listing	*.fis	non applicable
vertex_listing	non applicable	*.vis
tope_listing	*.tis	non applicable
verify_input	*.solved	*.solved
preprojection	*sub.ine	non applicable
	and *.ext

If you wish to specify the output file names different from default, simply run the program by

  % cdd   (cddf+, cddr+)

and input desired file names at each of file name requests. Even after you run cdd this way, one can change to the automatic mode by inputing the input file name with additional semicolon, e.g. ``test.ine;''.

To test cdd/cdd+, it is suggested to run cdd+ with sample input files which are stored in subdirectories ine and ext.
