23.5. Greedy Strategy in Interval Scheduling

Try these first

1. 1.

   Define the greedy strategy.

   Hint

   Think about immediate benefits in decision-making.

2. 2.

   What is the interval scheduling problem?

   Hint

   Consider how overlapping requests affect outcomes.

3. 3.

   What is the primary goal in the interval scheduling problem?

   • Maximize the total weight
   • Maximize the number of bookings
   • Minimize overlapping requests

   Hint

   Think about what the objective is when managing schedules.

4. 4.

   True or False: The greedy strategy is guaranteed to find an optimal solution for all kinds of scheduling problems.

   • True
   • False

   Hint

   Consider cases when weights complicate the decision.

5. 5.

   Given the intervals (1, 4), (2, 5), (3, 6), and associated weights of 3, 2, and 6 respectively, determine the optimal schedule using a dynamic programming approach.

   Hint

   Break down the intervals into sub-problems and calculate the total weights.

6. 6.

   Devise a greedy algorithm for the weighted interval scheduling problem and analyze its efficiency compared to dynamic programming.

   Hint

   Consider how choosing higher weights over finishing times may not always yield the best outcome.
