 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 agentA copy of a magazine A drivethru menu board A GPS with a destination A grocery store checkout An improvement over goal based agents, helpful when achieving the desired goal is not enough We might need to consider a cost For example, we may look for quicker, safer, cheaper trip to reach a destination This is denoted by a utility function A utility agent will chose the action that maximizes the expected utility

Goal based agent example

Goal based agent example-Question 4 For each of the four main types of agent Simple reflex agents, Reflex agents with an internal state, Goal based agents, and Utility based agents For example, they represent the interaction of a Simple reflex agent with its environment as Try to come up with alternative/better ways of representing those four types of agentGoalBased 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

Give an example, or show why one is not possibleGOAL is an agent programming language for programming cognitive agentsGOAL agents derive their choice of action from their beliefs and goals The language provides the basic building blocks to design and implement cognitive agents by programming constructs that allow and facilitate the manipulation of an agent's beliefs and goals and to structure its decisionmaking Utility Based Agent Determines the best way to reach the goal Learning Agent Analyzes information to make improvements 26) This exercise explores the differences between agent functions and agent programs A) Can there be more than one agent program that implements a given agent function?

 Utilitybased agents These types of agents are concerned about the performance measure The agent selects those actions which maximize the performance measure and devote towards the goal Example The main goal of chess playing is to 'checkandmate' the king, but the player completes several small goals previously Note Utilitybased agents keep track of its environment, and before reaching its main goal, it completes several tiny goalsUtilitybased 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 elementAt other times, however, the agent must consider also search and planning Decision making of this latter kind involves consideration of the future Goal based agents are commonly more flexible than reflex agents

An intelligent agent may learn from the environment to achieve their goals A thermostat is an example of an intelligent agent Following are the main four rules for an AI agent Rule 1 An AI agent must have the ability to perceive the environment Rule 2 The observation must be used to make decisions Rule 3 Decision should result in an actionParticularly useful when i there are conflicting goals Utility Based Agent Determines the best way to reach the goal Learning Agent Analyzes information to make improvements 26) This exercise explores the differences between agent functions and agent programs A) Can there be more than one agent program that implements a given agent function?

 Agentbased modeling relies on simulating the actions and interactions of autonomous agent s to evaluate their effects on the system It is often used to predict the projections that we will obtain given a complex phenomena The main purpose is to obtain explanatory insight on how the agents will behave given a particular set of rulesSee Fig 211 in text;Learning Agent Simple reflex agents Simple reflex agents ignore the rest of the percept history and act only on the basis of the current percept Percept history is the history of all that an agent has perceived to date The agent function is based on the conditionaction

 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 regionsWhich of these might be an example of a goalbased agent?Utilities indicate preferences among states;
