Reactive Agent System

A Reactive Agent System is a stimulus-response minimal autonomy software agent system that operates through immediate responses to environmental stimuli.

• AKA: Reflex Agent, Stimulus-Response Agent, Condition-Action Agent.
• Context:
  • It can typically execute Condition-Action Rules without internal state.
  • It can typically respond to Current Percepts via direct mapping.
  • It can typically implement Simple Behaviors through lookup tables.
  • It can typically process Environmental Inputs using sensor readings.
  • It can typically generate Immediate Actions without deliberation.
  • ...
  • It can often operate with Minimal Memory Requirements for efficient execution.
  • It can often provide Fast Response Times through direct coupling.
  • It can often demonstrate Predictable Behaviors via deterministic rules.
  • It can often exhibit Limited Flexibility in novel situations.
  • ...
  • It can range from being a Simple Reactive Agent System to being a Complex Reactive Agent System, depending on its reactive agent system rule sophistication.
  • It can range from being a Pure Reactive Agent System to being a Hybrid Reactive Agent System, depending on its reactive agent system architecture purity.
  • It can range from being a Single-Layer Reactive Agent System to being a Multi-Layer Reactive Agent System, depending on its reactive agent system processing depth.
  • It can range from being a Domain-Specific Reactive Agent System to being a General-Purpose Reactive Agent System, depending on its reactive agent system application scope.
  • ...
  • It can implement Subsumption Architecture for behavior layering.
  • It can utilize Production Rule Systems for action selection.
  • It can employ Finite State Machines for behavior encoding.
  • It can leverage Neural Networks for pattern recognition.
  • It can incorporate Fuzzy Logic for uncertain reasoning.
  • ...
• Example(s):
  • Simple Reactive Agent Systems, such as:
    • Thermostat Control Agent responding to temperature changes.
    • Spam Filter Agent classifying email messages.
    • Motion Detector Agent triggering security alerts.
  • Game Reactive Agent Systems, such as:
    • Pac-Man Ghost Agent following movement patterns.
    • Chess Opening Agent executing opening moves.
    • Racing Game Opponent following track waypoints.
  • Robotic Reactive Agent Systems, such as:
    • Obstacle Avoidance Robot using proximity sensors.
    • Line Following Robot tracking path markers.
    • Light-Seeking Robot moving toward light sources.
  • ...
• Counter-Example(s):
  • Deliberative Agent System, which uses planning and reasoning.
  • Learning Agent System, which modifies behavior through experience.
  • Goal-Based Agent System, which pursues objectives through planning.
