pddlnet.dll (nuget): This is a PDDL parser library using an ANTLR 4 grammar that provides a very simple interface to     interact with domain-problems.     This library publishes one object class whose API exposes methods for obtaining:      * The initial state.     * The goals.     * The list of operators.     * The positive and negative preconditions and the positive and negative effects.     * The _grounded_ states of a given operator (grounded variables, preconditions and effects).      This is enough for the user to focus on the implementation of state-space or plan-space search algorithms.      See examples at the project site.
