Tennis is a racket sport that is played by two opposing players on S sets. Each set consists of at least Kgames. A set is won by a player if that player wins at least K games and at least 2 games more than theopponent. Once a set is won, the set is ended and the match continues to a new set (if any) where bothplayers start from 0 game won for that new set.For example, let K = 6, then a set can be ended with any of the following.• P1 (Player 1) wins 6 games while P2 (Player 2) wins 3 games → P1 wins the set.• P1 wins 7 games while P2 wins 9 games → P2 wins the set.On the other hand, a set cannot be ended with any of the following.• P1 wins 6 games while P2 wins 5 games → no player wins at least 2 games more than the opponent.• P1 wins 0 game while P2 wins 5 games → no player wins K = 6 games.• P1 wins 7 games while P2 wins 0 games → the set is already ended when P1 won the first 6 games.• P1 wins 8 games while P2 wins 5 games → the set must already be ended before it reaches this…
Write a class that when given the MDG and the number of iterations it applies the Munch clustering algorithm and return the clustering arrangement as output. This class will contain the components from the previous questions. Appendix A contains the pseudocode of the Munch clustering algorithm using the Random Mutation Hill Climbing algorithm. However, any single population heuristic search algorithm can be used.

Directions: Use the set- roaster notation to write the following sets, and determine the number of elements that are in a set. 1. Let A={ 1,2,3 }, B={ 3,1,2 },and C={ 1,1,2,3,3,3 }. What are the elements of A? B? and C? How are A, B and C related? 2. Let A={ w,x,y,z } and B= { a,b }. Find AxB? And BxB?

Taxi zum zum def taxi_zum_zum(moves): A taxicab cruising around the Manhattan street grid starts at the origin (0,0) of the infinite twodimensional lattice grid of all pairs of integers, denoted by ℤ2. This taxicab has a direction that is always one of the four main compass directions, initially heading north. The taxicab then faithfully executes the given sequence of moves, guaranteed to be a string made up of the characters 'L' for turning 90 degrees left (while standing in place), 'R' for turning 90 degrees right (ditto), and 'F'for moving one step forward towards the current heading. This function should return the final position of the taxicab in the integer grid coordinates of this infinitely spanning Manhattan. moves expected result 'RFRL' (1, 0) 'LFFLF' (-2, -1) 'LLFLFLRLFR' (1, 0) 'FR' * 1000 (0, 0) 'FFLLLFRLFLRFRLRRL' (3, 2)
