actorsuch

Actorsuch is a term used in theoretical discussions of agent-based computing to denote a class of autonomous agents that combine the actor model with constraint-based reasoning. An actorsuch agent processes messages asynchronously and maintains state locally, while also representing a set of constraints that specify desirable or permissible configurations of the system and other agents.

In operation, an actorsuch agent selects actions by solving a constrained optimization problem over its knowledge base and the messages received. The such that aspect is core: goals are expressed as constraints of the form “such that property P holds” and agents communicate to achieve consistency. The approach supports dynamic environments by updating constraints in response to events and by propagating new information to other actors.

Origins and usage: The term is used in some academic and speculative discussions to illustrate a hybrid of the actor model and declarative programming. It is not a formal standard or widely adopted pattern, but serves as a conceptual bridge for exploring coordinated behavior, policy enforcement, and reasoning under uncertainty in distributed systems.

Variants and implementations: Real-world implementations conceptually resemble actors with embedded constraint solvers or with interfaces to external constraint programming engines. Prototypes may use existing actor frameworks (for example, message-passing libraries) alongside solvers to compute actions that satisfy current constraints while remaining responsive to new messages.
