1. If a player （quit/quits), he will （keep/keeping) his points for that game.

Find all critical points for the function,and classify each as a relative maximum,relative minimum, or saddle point.

听力原文：W: Dr. Anderson, could you please clarify the requirements for this course? Some of us are a little bit confused about the final examination.

M: Oh? Well, you have two options in this course. You can either take a final examination or you can write a research paper instead.

W: Excuse me, Dr. Anderson. That's the point I need. you to clarify. What kind of research paper did you have in mind? A study? A report? A book review, perhaps?

M: A report. A summary really, based upon current research in the field.

W: How long should the report be7

M: Length is really not important. I should think that it would take at least ten pages in order to develop the topic, however.

W: And should we check the topic with you before we begin writing?

M: You may, if you wish. But the only requirement is that it relate to current trends in United States foreign policy. Are you considering writing a paper, Jane?

W: I'm not sure. I think that I'd like to know a little bit more about the examination.

M: All right. One hundred multiple-choice questions covering both the lectures and the outside readings.

W: Didn't you say that you would give us one hour for the examination?

M: Yes, I did.

Consider the game tree shown below. As in the previous problem, triangles that point up, such as the top node (root), represent choices for the maximizing player; triangles that point down represent choices for the minimizing player. The circular nodes represent chance nodes in which each of the possible actions may be taken with equal probability. The square nodes at the bottom represent leaf nodes. Assuming both players act optimally, carry out the expectiminimax search algorithm. Enter the values for the letter nodes in the boxes below the tree.Input Answers Here G:

三、TURE OR FALSE: (10 points, 2 points for each) 1. The principal properties that can be exploited to separate proteins form each other are size, charge, hydrophobicity and affinity for other molecules. （ ） 2. RNA transcription is asymmetric. It means the coding strand is always the same strand. （ ） 3. There is a loop of 12 amino acids anchored by two cysteine and two histidine residues that tetrahedrally co-ordinate a zinc ion in C2H2 zinc finger. （ ） 4. Ribozymes are catalytic RNA molecules that can catalyze particular biochemical reactions in the absence of protein. （ ） 5. Both shearing and sonication denature the DNA. They also reduce the length of DNA. （ ）

Q2 Expectiminimax Consider the game tree shown below. As in the previous problem, triangles that point up, such as the top node (root), represent choices for the maximizing player; triangles that point down represent choices for the minimizing player. The circular nodes represent chance nodes in which each of the possible actions may be taken with equal probability. The square nodes at the bottom represent leaf nodes. Assuming both players act optimally, carry out the expectiminimax search algorithm. Enter the values for the letter nodes in the boxes below the tree.Input Answers Here A:

Q4 Alpha-Beta Pruning Consider the game tree shown below. Triangles that point up, such as at the top node (root), represent choices for the maximizing player; triangles that point down represent choices for the minimizing player. Assuming both players act optimally, use alpha-beta pruning to find the value of the root node. The search goes from left to right; when choosing which child to visit first, choose the left-most unvisited child. In the first set of boxes below, enter the values of the labeled nodes. Then, select the leaf nodes that don't get visited due to pruning. Hint: Note that the value of a node where pruning occurs is not necessarily the maximum or minimum (depending on which node) of its children. When you prune on conditions V>βV>βV>β or V<αv<αv<α, assume that the value of node is vvv. src="http://static.jiandati.com/d80de79-chaoxing2016-857389.png"> Enter the values of the labeled nodes A:
