Fast Downward uses the COIN-OR LP Solver (CLP) with the Open Solver Interface. To use the LP solver (for example, for optimal cost partitioning of landmarks heuristic), follow these instructions:
Instructions for Building Fast Downward with LP Solver
- Go to downward/search/lp/
- run ./setup (this will build the LP solver, this might take a few minutes)
- In downward/search, give the USE_LP_CLP=1 flag to make
- make USE_LP_CLP=1
- make USE_LP_CLP=1 release
