Abstract

Scenario-Based Programming (SBP) is an approach to modeling and running complex, event-based, system behavior by composing narrower views of overall behavior. In this paper we introduce significant extensions to the strict interfaces by which scenarios in existing SBP frameworks specify what the system must, may, or must not do, and to the mechanisms that execute these scenarios: (i) we allow events with a multitude of variables and parameters; each event can become an entire model, and each event selection can be the selection of a major section of the new state of the system and the environment; (ii) we extend the basic request/block SBP interfaces with a rich set of composable constraints and functions, which can describe desired and undesired variable assignments, where each constraint may relate to all variables or to just a subset thereof; (iii) we introduce a central, application-agnostic mechanism for adding optimization to standard event selection; and (iv) we relate our method to Null-Space Behavior (NSB)—a successful compositional approach in control theory. We demonstrate these language-independent concepts through several use cases that are implemented in a variety of languages and solvers.
