Oct 01, 15 · GoalBased Agents are ModelBased Agents that set a specific goal and select the actions that lead to that goal This allows the agent to choose a goal state among multiple possibilities Planning activity is devoted to finding the sequence of actions that are able to achieve the agent's goals ( Russell and Norvig, 03 )Goalbased agents only distinguish between goal states and nongoal states It is also possible to define a measure of how desirable a particular state is This measure can be obtained through the use of a utility function which maps a state to a measure of the utility of the state• Goalbased • Utilitybased Agent Definition • Any entity that perceivesits environment through sensors and acts upon that environment through effectors • Examples (class discussion) human, robotic, softwareagents Perception • Signal from environment • May exceed sensory capacity Sensors • Acquires percepts • Possible limitations

What is goal based agent-Utilitybased agents A rational utilitybased agent chooses the action that maximizes the _____ of the action outcomes, that is, the utility the agent expects to derive, on average, given the probabilities and utilities of each outcomeAgent's procedural knowledge knowledge about the mechanisms that can be used by the agent in order to realize its intentions • The options available to an agent are directly determined by the plans an agent has an agent with no plans has no options • PRS agents have explicit representations of beliefs, desires (goals) and intentions
