Question 1.
What is a heuristic strategy?
Show hintHide hint
Think about methods that focus on immediate benefits.
Question 2.
Why is the brute-force approach often ineffective for job scheduling?
Show hintHide hint
Consider how many different ways you could arrange multiple jobs.
3Question 3.
What is the primary disadvantage of the brute-force approach?
- A. It guarantees optimal solutions
- B. It's computationally expensive
- C. It's quick to execute
Show hintHide hint
Consider the definition of brute-force.
4Question 4.
True or False: Heuristic strategies always provide the optimal solution.
- True
- False
Show hintHide hint
Remember the difference between heuristics and optimal methods.
Question 5.
You are managing a photo copying shop with three machines of varying speeds. Job A takes 1 hour on machine 1, 30 minutes on machine 2, and 45 minutes on machine 3. Job B takes 2 hours on machine 1, 90 minutes on machine 2, and 1 hour on machine 3. Devise a schedule that minimizes total completion time considering these parameters.
Show hintHide hint
Use a comparative chart to weigh machine speeds against jobs.
Question 6.
In a scenario where job deadlines overlap, propose a method to batch jobs that require similar processing times for more efficient scheduling.
Show hintHide hint
Think about grouping tasks that share characteristics.
