Trace the behavior of DPLL on the knowledge base in Figure 7.15 when trying to prove Q, and compare this behavior with that of the forward chaining algorithm.
Hotv long does it take to prove KB )= a using DIPLL when a is a literal already contained in KB? Explain.

This exercise looks into the relationship between clauses and implication sentences.a. Show that the clause (7P1 V . . . V TP, V Q) is logically equivalent to the implication sentence (PI A . A P,) + Q.b. Show that every clause (regardless of the number of positive literals) can be written in the
Minesweeper, the well-known computer game, is closely related to the wumpus world.A minesweeper world is a rectangular grid of N squares with M invisible mines scattered among them. Any square may be probed by the agent; instant death follows if a mine is probed. Minesweeper indicates the presence

Suppose the agent has progressed to the point shown in Figure 7.4(a), having perceived nothing in [1,1], a breeze in [2,1], and a stench in [1,2]. and is now concerned with the contents of [1,3], [2,2], and [3,1]. Each of these can contain a pit and at most one can contain a wumpus. Following the
Describe the wumpus world according to the properties of task environments listed in Chapter 2.
The minimax algorithm assumes that players take turns moving, but in card games such as whist and bridge, the winner of the previous trick plays first on the next trick.a. Modify the algorithm to work properly for these games. You may assume that a function WINNER(Si)s available that reports which
Implement the expectiminimax algorithm and the *-alpha-beta algorithm, which is described by Ballard (1983), for pruning game trees with chance nodes. Try them on a game such as backgammon and measure the pruning effectiveness of *-alpha-beta.
Develop a formal proof of correctness for alpha-beta pruning. To do this, consider the situation shown in Figure 6.15. The question is whether to prune node nj, which is a maxnode and a descendant of node nl. The basic idea is to prune it if and only if the minimax value of nl can be shown to be
Implement move generators and evaluation functions for one or more of the following games: Kalah, Othello, checkers, and chess. Constnuct a general alpha-beta game-playing agent that uses your implementation. Compare the eEect of increasing search depth, improving move ordering, and improving the
This problem exercises the basic concepts of gamle playing, using tic-tac-toe (noughts and crosses) as an example. We define X, as the number of rows, columns, or diagonals with exactly n X's and no 0's. Similarly, 0, is the number of rows, columns, or diagonals with just n 0's. The utility
Suppose that a graph is known to have a cycle cutset of 110 more than k nodes. Describe a simple algorithm for finding a minimal cycle cutset whose runtime is not much more than O(nk)fo r a CSP with n variables. Search the literature for methods for finding approximately minimal cycle cutsets in
AC-3 puts back on the queue every arc (XI,, Xi)w henever any value is deleted from the domain of Xi, even if each value of XI, is consistent with several remaining values of Xi.Suppose that, for every arc (XI,, Xi), we keep track of the number of remaining values of Xi that are consistent with each
Use the AC-3 algorithm to show that arc consistency is able to detect the inconsistency of the partial assignment { WA = red, V = blue) for the probllem shown in Figure 5.1.
Figure 5.5 tests out various algorithms on the n-queens problem. Try these same algorithms on map-coloring problems generated randomly as follows: scatter n points on the unit square; selecting a point X at random, connect X by a straight line to the nearest point Y such that X is not already
Explain why it is a good heuristic to choose the variable that is most constrained, but the value that is least constraining in a CSP search.
How many solutions are there for the map-coloring problem in Figure 5. l?
Define in your own words the terms constraint satisfaction problem, constraint, backtracking search, arc consistency, backjumping and rnin-conflicts.
as an example.a. Repeat Exercise 3.16 using hill climbing. Does your agent ever get stuck in a local minimum? Is it possible for it to get stuck with convex obstacles?b. Construct a nonconvex polygonal environment in which the agent gets stuck.c. Modify the hill-climbing algorithm so that, instead
In this exercise, we will examine hill climbing in the context of robot navigation, using the environment in Figure
Generate a large number of 8-puzzle and 8-queens instances and solve them (where possible) by hill climbing (steepest-ascent and first-choice variants), hill climbing with random restart, and simulated annealing. Measure the search cost and percentage of solved problems and graph these against the
Suppose that an agent is in a 3 x 3 maze environment like the one shown in Figure 4.18. The agent knows that its initial location is (1,1)1t,h at the goal is at (3,3),a nd that the four actions Up, Down, Left, Right have their usual effects unless blocked by a wall. The agent does not know where
On page 108, we defined the relaxation of the &-puzzle in which a tile can move from square A to square B if B is blank. The exact solution of this problem defines Gaschnig's heuristic (Gaschnig, 1979). Explain why Gaschnig's heuristic is at least as accurate as hl(misplaced tiles), and show cases
We saw on page 96 that the straight-line distance heuristic leads greedy best-first search astray on the problem of going from Iasi to Fagaras. However, the heuristic is perfect on the opposite problem: going from Fagaras to Iasi. Are there problems for which the heuristic is misleading in both
The heuristic path algorithm is a best-first search in which the objective function is f(n) = (2 - w)g(n) + wh(n). For what values of w is this algorithm guaranteed to be optimal? (You may assume that h is admissible.) What kind of search does this perform when w = O? When w = l? When w = 2?
Consider the vacuum-world problem defined in Figure 2.2.a. Which of the algorithms defined in this chapter would be appropriate for this problem?Should the algorithm check for repeated states?b. Apply your chosen algorithm to compute an optimal sequence of actions for a 3 x 3 world whose initial
On page 62, we said that we would not consider problems with negative path costs. In this exercise, we explore this in more depth.a. Suppose that actions can have arbitrarily large negative costs; explain why this possibility would force any optimal algorithm to explore the entire state space.b.
We can turn the navigation problem in Exercise 3.15 into an environment as follows:The percept will be a list of the positions, relative to the agent, of the visible vertices.The percept does not include the position of the robot! The robot must learn its own position from the map; for now, you can
Consider the problem of finding the shortest path between two points on a plane that has convex polygonal obstacles as shown in Figure 3.22. Ths is an idealization of the problem that a robot has to solve to navigate its way around a crowded environment.a. Suppose the state space consists of all
Describe a state space in which iterative deepening search performs much worse than depth-first search (for example, O(n2) vs. O(n)).
Prove that uniform-cost search and breadth-first search with constant step costs are optimal when used with the GRAPH-SEARCH algorithm. Show a state space with varying step costs in which GRAPH-SEARCH using iterative deepening finds a suboptimal solutj~on.
On page 79, we mentioned iterative lengthening search, an iterative analog of uniform cost search. The idea is to use increasing limits on path cost. If a node is generated whose path cost exceeds the current limit, it is immediately discarded. For each new iteration, the limit is set to the lowest
Implement two versions of the successor function for the 8-puzzle: one that generates all the successors at once by copying and editing the 8-puzzle data structure, and one that generates one new successor each time it is called and works by modifying the parent state directly (and undoing the
Consider the n-queens problem using the "efficient" incremental formulation given on page 67. Explain why the state space size is at least $'% and estimate the largest n for which exhaustive exploration is feasible. (Hint: Derive a lower bound on the branching factor by considering the maximum

Consider a modified version of the vacuum environment in Exercise 2.7, in which the agent is penalized one point for each movement.a. Can a simple reflex agent be perfectly rational for this environment? Explain.b. What about a reflex agent with state? Design such an agent.c. How do your answers to
