3. An interschool basketball tournament is being held at the Olympic sports complex. There are multiple basketball courts. Matches are scheduled in parallel, with staggered timings, to ensure that spectators always have some match or other available to watch. Each match requires a team of referees and linesmen.
Two matches that overlap require disjoint teams of referees and linesmen. The tournament organizers would like to determine how many teams of referees and linesmen they need to mobilize toeectively conduct the tournament. To determine this, which graph theoretic problem do the organizers have to solve?
(a) Find a minimal colouring.
(b) Find a minimal spanning tree.
(c) Find a minimal cut.
(d) Find a minimal vertex cover.
4. We have constructed a polynomial time reduction from problem A to problem B. Which of the following is not a possible scenario?
(a) We know of polynomial time algorithms for both A and B.
(b) We only know of exponential time algorithms for both A and B.
(c) We only know an exponential time algorithm for A, but we have a polynomial time algorithm for B.
(d) We only know an exponential time algorithm for B, but we have a polynomial time algorithm for A.
5. When the procedure terminates, the array A has been:
(a) Sorted in descending order
(c) Reversed
(b) Sorted in ascending order
(d) Left unaltered
6. The number of times the test A[j] > A[m] is executed is:
