Metric-FF

Website: https://fai.cs.uni-saarland.de/hoffmann/metric-ff.html

Original instructions:

This directory contains the C implementation of Metric-FF, as it was
used in the 3rd international planning competition. Build the planner
by typing

make

Which produces an executable named

ff

Usage should be self-explanatory. Running ff without any parameters
prints out a brief help information about the parameters that are
applicable, which basically come down to specifying the domain and
problem files.

Have fun,

Pre-requisites

You will need Flex, Bison, make, and a C compiler (tested working with gcc and clang).

Go into the version folder v1.0 or v2.1 that you need, then adjust the makefile as needed, by editing the CC variable to gcc or clang.

Windows

On Windows, get Flex and Bison from: https://sourceforge.net/projects/winflexbison/files/latest/download and extract win_flex.exe, win_bison.exe and the data/ folder into the project root directory.

You will also need make. This comes pre-installed on most Linux/Mac distributions, but needs special set-up on Windows. The easiest way to get it is to install Chocolatey and then install make via choco install make. Use Git Bash instead of CMD/PowerShell.

Alternatively, if you use MSYS2 with MinGW for the GCC compiler, MSYS2 provides make along with many other unix utilities.

Building

1. Navigate into the version folder you need (v1.0 or v2.1)
2. Run make
3. (optionally) run make clean to delete the intermediate files created during compilation.
