In order to obtain a set of domains to run the code on (if not present already),
I recommend cloning from 
https://bitbucket.org/aibasel/downward-benchmarks
(in directory downward/, so the repository is in the
directory downward/downward-benchmarks).

The code was developed and tested on this set of domains.

Compile the code using: ./build.py -j2

Call landmark-meta-search by using:
./fast-downward.py task.pddl --search "landmark_meta_search(lm_factory=?,heur=?,subheur=?)"
Replace task.pddl with a task.pddl-file, and ? with any options implemented in Fast Downward.
For example:
./fast-downward.py downward-benchmarks/gripper/prob01.pddl --search "landmark_meta_search(lm_factory=lm_zg(),heur=ff(),subheur=ff())"
