Release<T> class final

Represents the temporal operator RELEASE (R).

Formula: left R right (Equivalent to !( (!left) U (!right) ))

Evaluates to true at time t if the right formula holds at time t and continues to hold up to and including the point where left first becomes true. If left never becomes true, right must hold indefinitely from t onwards.

Intuitively, right must always be true unless left "releases" it by becoming true at some point (at which point right must also be true).

Evaluation Details:

  • Release is the dual of Until.
  • This evaluator implements left R right using its equivalence: !(!left U !right).
