Design and explain a generic m-round winner tournament, Round-Winner-Tournament(P,m), for players P, in which the participants are matched randomly in each round 0, 1,...,m 1, and the winners advance to the next round. Following round m 1, the champion is chosen at random from among the remaining participants. This tournament structure, interestingly, contains the following special cases: m = 0 is a random selection tournament, m = 1 is a random pairing tournament, and m = lg |P| is a single elimination seeding tournament.
Create and explain a generic m-round winner tournament for players P called Round-Winner-Tournament(P,m), where participants are matched at random in rounds 0, 1,..., m 1 and the winners advance to the next round. The winner is chosen at random from the remaining participants after round m 1. It's interesting to note that this tournament structure contains the following special cases: the random selection tournament (m = 0), the random pairing tournament (m = 1), and the single elimination seeding tournament (m = lg |P|).
Sum of Squared Errors: Remember from your statistics courses that if two random variables X and Y are related by a relation YaX+b and you had a set of observations {(1, 1), (2, 2)..... (z.)). then for every estimated values of a and b, the Sum of Squared Errors (SSE) was defined as in the following formula. SSE(-ar-b)². 1-1 The less SSE, the better a and b are estimated. Consider the following fixed list. In this list each sub-list of length two is standing for one pair (z.). Write a function that recieves two numbers a and b and returns the associated SSE.

You are organizing a conference that has received n submitted papers. Your goal is to get people to review as many of them as possible. To do this, you have enlisted the help of k reviewers. Each reviewer i has a cost sij for writing a review for paper j. The strategy of each reviewer i is to select a subset of papers to write a review for. They can select any subset S; C {1,2, ..., n}, as long as the total cost to write all reviews is less than T (the time before the deadline): 2 Sij 1. (b) Show that for B = 2 this fraction is close to 1/3. [Hint: You can consider an instance with 3n + 1 papers and only n will be reviewed.]
