WeakUntil<T> class final

Represents the temporal operator WEAK UNTIL (W).

Formula: left W right (Equivalent to (left U right) || G(left))

Evaluates to true at time t if either the left formula holds indefinitely from t onwards, OR if the strong left U right condition holds (i.e., right eventually becomes true, and left holds until then). Unlike Until, right is not required to eventually become true.

Evaluation Details:

  • This evaluator implements left W right using its equivalence: G(left) || (left U right).
