Expert Solution & Answer
Chapter 5, Problem 1E
Explanation of Solution
- The translation uses the model of the opponent to fill in the opponent’s actions leaving the actions to be determined by the search algorithm.
- The search problem is given by
Initial state: P(S0) where S0 is the initial game state. P can be applied as the opponent may play first.
Actions: defined as in the game by ACTIONSs.
Successor function: RESULT′(s, a) = P(RESULT(s, a))
Goal test: goals are terminal states
Step cost: the cost of an action is zero.

6. Rod-cutting problem
Design a dynamic programming algorithm for the fol-
lowing problem. Find the maximum total sale price that can be obtained by
cutting a rod of n units long into integer-length pieces if the sale price of a piece
i units long is p; for i = 1, 2, ..., n. What are the time and space efficiencies
of your algorithm?

You and Alice and Bob are considering variants of the Pokemon problem. In the opti-
mization problem we are looking for the minimum set of packs, and there are multiple
ways to convert it to a decision problem (you probably used the standard method of
adding a threshold variable k above).
Alice considers the question "Is there a collection of packs of size 5 (or less) that includes
one of every card in the set?".
Bob considers the question "Is there a collection of packs of size [2] (or less) that
includes one of every card in the set?".
Are Alice and Bob's versions of the problem NP-complete? Either way, justify your answer
with a proof.
Correct answer will be upvoted else downvoted.
There are n focuses on an endless plane. The I-th point has facilitates (xi,yi) to such an extent that xi>0 and yi>0. The directions are not really integer.
In one maneuver you play out the accompanying activities:
pick two focuses an and b (a≠b);
move point a from (xa,ya) to either (xa+1,ya) or (xa,ya+1);
move point b from (xb,yb) to either (xb+1,yb) or (xb,yb+1);
eliminate focuses an and b.
Notwithstanding, the move must be performed if there exists a line that goes through the new organizes of, another directions of b and (0,0).
If not, the move can't be performed and the focuses stay at their unique directions (xa,ya) and (xb,yb), individually.
Input
The main line contains a solitary integer n (1≤n≤2⋅105) — the number of focuses.
The I-th of the following n lines contains four integers ai,bi,ci,di (1≤ai,bi,ci,di≤109). The directions of the I-th point are xi=aibi and yi=cidi.

To vanquish new grounds he intends to construct one Monument in every city. The game is turn-based and, since Monocarp is as yet beginner, he fabricates precisely one Monument for each turn. Monocarp has m focuses on the guide he'd prefer to control utilizing the developed Monuments. For each point he knows the distance among it and every city. Landmarks work in the accompanying manner: when implicit some city, a Monument controls all focuses at distance all things considered 1 to this city. Next turn, the Monument controls all focuses at distance all things considered 2, the turn after — at distance all things considered 3, etc. Monocarp will construct n Monuments in n turns and his domain will overcome all focuses that are constrained by somewhere around one Monument.

Computer science. deck is called arranged if the front qualities are in expanding request and the back qualities are in diminishing request. That is, if ai<ai+1 and bi>bi+1 for all 1≤i<n. To flip a card I implies trading the upsides of simulated intelligence and bi. You should flip some subset of cards (perhaps, none), then, at that point, put every one of the cards in any request you like. What is the base number of cards you should flip to sort the deck? Input The main line contains a solitary integer n (1≤n≤2⋅105) — the number of cards. The following n lines depict the cards. The I-th of these lines contains two integers ai,bi (1≤ai,bi≤2n).
