Subtask generator (used by the CEGAR heuristic).
goals
goals(order=hadd_down, random_seed=-1)
order ({original, random, hadd_up, hadd_down}): ordering of goal or landmark facts
original: according to their (internal) variable index
random: according to a random permutation
hadd_up: according to their h^add value, lowest first
hadd_down: according to their h^add value, highest first
random_seed (int [-1, infinity]): Set to -1 (default) to use the global random number generator. Set to any other value to use a local random number generator with the given seed.
landmarks
landmarks(order=hadd_down, random_seed=-1, combine_facts=true)
order ({original, random, hadd_up, hadd_down}): ordering of goal or landmark facts
original: according to their (internal) variable index
random: according to a random permutation
hadd_up: according to their h^add value, lowest first
hadd_down: according to their h^add value, highest first
random_seed (int [-1, infinity]): Set to -1 (default) to use the global random number generator. Set to any other value to use a local random number generator with the given seed.
combine_facts (bool): combine landmark facts with domain abstraction
original
original(copies=1)
copies (int [1, infinity]): number of task copies
