An utilitybased reflex agent is like the goalbased agent but with a measure of "how much happy" an action would make it rather than the goalbased binary feedback 'happy', 'unhappy' This kind of agents provide the best solution An example is the route recommendation system which solves the 'best' route to reach a destinationGoalbased agents, on the other hand, can succeed by considering future actions and the desirability of their outcomes PROBLEMSOLVING This chapter describes one kind of goalbased agent called aproblemsolving agent AGENT Problemsolving agents think about the world usingatomic representations, as described inGoal based agent is one which choose its actions in order to achieve goals It is a problem solving agent and is more flexible than model reflex agentGoal based agent consider the future actions The agents uses goal information to select between possible actions in the current stateTwo aspect of goal based agents are searching and planning

A goalbased agent, in principle, could reason that if the car in front has its brake lights on, it will slow down From the way the world usually evolves, the only action that will achieve the goal of not hitting other cars is to brake Although the goalbased agentAgent Frameworks GoalBased Agents 1 Agent Sensors Effectors Goals What action I should do now Environment State How world evolves What my actions do What world is like now What it will be like if I do action A Agent Frameworks GoalBased Agents 2 Implementation and Properties • Instantiation of generic skeleton agent Figure 211Link for Simple reflex agents https//wwwyoutubecom/watch?v=KZFfbebQPAU&t=218sLink for Model Based Agents https//wwwyoutubecom/watch?v=xKxh3fQwU8E&t=1
Jan 17, · As the name says, GoalBased Agents have targets or goals that they need to achieve and don't work on simple reactive measures, goalbased agents are supposed to act to achieve the specified goal in the long term A goalbased agent uses searching and planning to act in the most efficient solution to achieve the goalLike the ModelBased Agents, GoalBased agents also have an internal model of the game state Where as ModelBased Agents only need to know how to update their internal model of the game state using new observations, Goalbased agents have the additional requirement of knowing how their actions will affect the game stateAn example of a goalbased agent A method that a goalbased agent uses to arrive at its goal The concept of targeting a goal and determining the correct actions that are needed to reach it
