Answer (1 of 3) Goal and utility could be considered ways of defining desire and happiness in intelligent agents enwikipediaorg/wiki/Intelligent_agent#Goal For an example of a nongoal based utility agent consider a form of a partisan sudoku in which players compete to control regions on the gameboard by placement of weighted integers In a game with 9 regions, the goal based agent seeks to control a specific number of regions at the end of playIf the agent is conservative, the goal might be 5 regions A Goal Based Agent takes decisions based on how far they are currently from reaching their goals A goal is nothing but the description of a desirable situation Every agent intends to reduce their distance from the goal This allows the agent an option to choose from multiple possibilities for selecting the best route in order to reach the goal state
Goal Based Agents
Goal based agent and utility based agent
Goal based agent and utility based agent- Goalbased agent program function GOALBASEDAGENT(percept) returns an action persistent state, the agent's current conception of the world state goal, a description of what the agent would like to achieve rules, a set of conditionaction rules action, the most recent action, initially none A goalbased agent combines modelbased agent's model with a goal To reach its goal it often uses Search and Planning algorithms Goal based agents usually less efficient but more flexible than reflexbased agents A goal basedagent can suit itself based

Utilitybased agents the agent is aware of a utility function that estimates how close the current state is to the agent's goal Learning Agents Agents capable of acquiring new competence through observations and actions Components learning element (modifies the performance element) performance element (selects actions) feedback element"A simple reflex based agent does not care about meeting the utility of the user" True;GoalBased Agent 19 Choose actions so as to achieve a (given or computed) goal A goal is a description of a desirable situation Keeping track of the current state is often not enough need to add goals to decide which situations are good Deliberative instead of reactive May have to consider long sequences of possible actions before deciding
All of the above; The reflex agents are known as the simplest agents because they directly map states into actionsUnfortunately, these agents fail to operate in an environment where the mapping is too large to store and learn Goalbased agent, on the other hand, considers future actions and the desired outcomes Here, we will discuss one type of goalbased agent known as a problemsolving agentIn this chapter, we consider the design of goalbased agents The specification and design of goalbased agents involves answering the following questions 1 What is the goal to be achieved?
Goalbased agents Goalbased agents further expand on the capabilities of the modelbased agents, by using "goal" information Goal information describes situations that are desirable This provides the agent a way to choose among multiple possibilities, selecting the one which reaches a goalA 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 Skills Practiced Information recallIntelligent system Goal Based Agent Implementation of a kind of goal based agent Problem solving agent The program has two types of searches implemented Uninformed (IDS) and Informed (A*) search Astar search has four different heuristics two good and two notsogood heuristics to analyze how a good heuristic can give better results

Answer & Explanation 2) State whether the following condition is true or false? RN "The agent program can combine this goal information with the model (the same information as was used in the modelbased reflex agent) to choose actions that achieve the goal" RN "Figure 213 A modelbased, goalbased agent It keeps track of the world state as well as a set of goals it is trying to achieve, and chooses an actionPlease Like Share & SubscribeIntroduction to Artificial Intelligence a modern approach, types of agent, simple reflex agent, Model Based Reflex model

This is because, GoalBased Agents use their internal model to test out strategies When they know how their actions will affect the game state, they can find out the different states each move will lead to Then based on the utility of these, they choose the best strategy Goalbased agents and Utilitybased agents has many advantage in terms of flexibility and learning Utility agents make rational decisions when goals are inadequate 1) The utility function specifies the appropriate trade off 2) Utility provides likelihood of success can be weighted against the importance of the goals– the agent's model of the world – usually a set of discrete states – eg, in driving, the states in the model could be towns/cities • Goal State(s) – a goal is defined as a desirable state for an agent – there may be many states which satisfy the goal • eg, drive to a town with a skiresort3 Goal – based agents 4 Utility – based agents 1 Simple reflex agents These agents
