Question 1.
Define the term 'Greedy Algorithm.'
Show hintHide hint
Think about how such decisions can affect the outcome.
Question 2.
What is the primary goal of interval scheduling?
Show hintHide hint
Consider the implications of overlapping time slots.
3Question 3.
What is a greedy algorithm?
- A method that guarantees optimal solutions.
- An approach that makes locally optimal choices.
- A strategy that avoids all risks.
Show hintHide hint
Remember the nature of decision-making.
4Question 4.
True or False: The finish-time strategy always yields an optimal solution in interval scheduling.
- True
- False
Show hintHide hint
Consider the foundational proof discussed in class.
Question 5.
Given the intervals [(0, 5), (1, 2), (3, 4), (2, 3), (4, 6)], find the maximum number of non-overlapping intervals using the finish-time strategy.
Show hintHide hint
Pay attention to finish times and overlaps.
Question 6.
Demonstrate the failure of the shortest interval strategy with an example of your own design.
Show hintHide hint
Analyze how overlaps change outcomes.
