Reproducibility Variable Result LLM Response
Research Type Experimental We implemented the state equation heuristic and the potential heuristic that optimizes the heuristic value of the initial state in the Fast Downward planning system (Helmert 2006). All our experiments were run on the set of tasks from optimal tracks of IPC 1998 2011, limiting runtime to 30 minutes and memory usage to 2 GB. Each task ran on a single core of an Intel Xeon E5-2660 processor (2.2 GHz). Linear programs were solved with IBM s CPLEX v12.5.1. Table 1 shows the number of solved tasks (coverage) for the tested configurations. Figure 2 shows that using general operator cost partitioning substantially reduces the number of expansions. Figure 3: Number of solved tasks per time for the potential and the state equation heuristic.
