Features

Changelog:

• version 0.0.1 - Initial release. Support for discrete PDDL domain and problem parsing.
• version 1.0.0 - Major extension to support PDDL 2.1 in terms of numeric actions.
• version 1.1.0 - Added support for Metric-FF solutions parsing.
• version 1.2.0 - Added support for ENHSP solution parsing.
• version 1.3.0 - Added problem generators for some domains used in the experiments.
• version 1.4.0 - Added negative preconditions for actions.
• version 2.0.0 - Added support for multi-agent PDDL domains and problems.
• version 2.1.0 - Added support for more complex type of multi-agent trajectories to support non-trivial interactions.
• version 2.2.0 - Added support for domains with disjunctive numeric preconditions.
• version 3.0.0 - Added support for conditional effect without existential quantification and only conjunctive conditions.
• version 3.1.0 - Added support for universal effects containing only conjunctive conditions.
• version 3.1.4 - Added support for inapplicable actions and fixed a minor logical bug in the universal effects.
• version 3.3.0 - Added support for nested action schemas including universal preconditions.
• version 3.5.0 - Added simplification of numeric expression. This helps to prevent getting too complicated preconditions.
• version 3.5.7 - Added support for problem exportation to PDDL from a problem object.
• version 3.5.8 - Fixed a bug that displayed power expressions in PDDL even though this is not supported by the language.
• version 3.6.5 - performance boost for the tokenizer - credit @yarin-benyamin.
• version 3.7.0 - Added the ability to simplify preconditions by eliminating variables that are redundant and thus reducing the general size of the conditions.
