With PDDL, Boolean variables are created from the PDDL predicates. With PDDL, Boolean variables are created from the PDDL predicates.
Variables ared named after the PDDL predicates, `variable(<PDDL predicate>).` Variables ared named after the PDDL predicates, `variable(<PDDL predicate>).`
Each variable contains exactly two values (one true, one false) of the form `value(<PDDL predicate>, <bool>)`. Each variable contains exactly two values (one `true`, one `false`) of the form `value(<PDDL predicate>, <bool>)`.
Note that with PDDL, variables and values are named identically. Note that with PDDL, variables and values are named identically.

### Initial State

The initial state contains all variable assignments that hold before executing any actions.
Note that with PDDL, the initial state might not assign values to all variables. Instead, unassigned values have to be assigned `false` manually.
