lp2pb

Lp2pb is a translation tool that translates ground ASP (lparse smodels) to PB-constraints (.OPB).

Manual (linux)

Compilation

The translator consists of multiple c++ files. Install 'make' and call it inside the root folder.

make

Executables

This tool makes use of 3 other tools to translate its input; lp2sat, lp2lp and lp2normal.
The executables for these should be in your PATH.
By calling:

make path

the latest versions (at the moment) are added to your ~/bin folder.
Make sure this folder is included in your PATH variable.

export PATH=~/bin:$PATH

OR add following line to ~/.bashrc:

export PATH="/home/$USER/bin:$PATH"

and restart your terminal or call:

source ~/.bashrc

If you would want another version for any of these tools you can put them in your PATH yourself using the correct names:

• lp2lp2
• lp2normal
• lp2sat

Usage

The translator expects smodels input, see Appendix B here.

To run the application:

./lp2pb <-i inputfile> <-o outputfile>

Input and output files are optional, if not provided standard input and output is used.
