1. Why do monetarists dislike the PSNCR?
2. What happens to the national debt if a public-sector debt repayment occurs?
3. What has happened to the national debt in real terms since 1945?
1. Why do NFL, NBA, and NHL teams tend to sell out while MLB teams do not 2. If P = $150 – 0.005 × Q, what is the equation for total revenue? 3. What is the relationship between market size and win in North American pro sports? Answer this question using both deductive and inductive analysis.
1. Why not solve the knapsack problem in the same way as the matrix-chain and optimum binary search tree problems: by minimizing, for k from I to M, the sum of the best value achievable for a knapsack of size k and the best value achievable for a knapsack of size M-k?
2. Extend the program for the shortest-paths problem to include a procedure paths 
that fills an array path with the shortest path from i to j. This procedure should take time proportional to the length of the path each time it is called, using an auxiliary data structure built up by a modified version of the program given in Chapter 32.
1. Why was the consultant not allowed to teach the methodology in ferris health management?
1. Write an OpenGL program that renders a cube with six faces of different colors. Form the cube from six quadrilaterals, making sure that the front faces are facing outwards. If you already know how to perform rotations, let your program include the ability to spin the cube around.(Ref er to Chapter II and see the Wrap Torus program for code that does this.)
If you rendered the cube using triangles instead, how many triangles would be needed?
2. Repeat question 1. but render the cube using two quad strips, each containing three quadrilaterals.
3. Repeat question 1. but render the cube using two triangle fans.
1. Why is shuffling a dataset before conducting k-fold CV generally a bad idea in finance? What is the purpose of shuffling? Why does shuffling defeat the purpose of k-fold CV in financial datasets?
2. Take a pair of matrices (X, y), representing observed features and labels. These could be one of the datasets derived from the exercises in Chapter 3.
(a) Derive the performance from a 10-fold CV of an RF classifier on (X, y), without shuffling.
(b) Derive the performance from a 10-fold CV of an RF on (X, y), with shuffling.
(c) Why are both results so different?
(d) How does shuffling leak information?
1. Write a program to find the longest simple path from x to y in a given weighted graph.
2. Could there be an algorithm which solves an NP-complete problem in an average time of N log N , if P ¢ NP? Explain your answer.
3. Give a nondeterministic polynomial-time algorithm for solving the partition problem.
1. Why is a choice made when resources are allocated?
2. What is the difference between a need and a want?
3. What role does government play in a market economy?
1. Write a program to solve the knapsack problem of Chapter 42 when the sizes can be real numbers.
2. Write a program to count the number of spanning trees of a set of N points in the plane with no intersecting edges.
3.
1. Why does IVY use an invalidation scheme for consistency instead of an update scheme?
2. Some machines have a single instruction that, in one atomic action, exchanges a register with a word in memory. Using this instruction, it is possible to implement semaphores for protecting critical regions. Will pro-grams using this instruction work on a page-based DSM system? If so, under what circumstances will they work efficiently?
