20.8. Conclusion

Try these first

1. 1.

   Define lateness in the context of job scheduling.

   Hint

   Consider what happens if a job finishes after its deadline.

2. 2.

   What does a greedy algorithm do?

   Hint

   Think about decision-making processes.

3. 3.

   What is the goal of the Minimizing Lateness problem?

   • Minimize total processing time
   • Minimize the maximum lateness
   • Maximize resource allocation

   Hint

   Focus on deadlines rather than total completion time.

4. 4.

   True or False: Selecting jobs by shortest processing time always results in the minimum lateness.

   • True
   • False

   Hint

   Remember the counterexample mentioned.

5. 5.

   Consider a set of jobs with the following times and deadlines: Job A (2, 5), Job B (1, 3), Job C (3, 8). Create an optimal schedule minimizing lateness and calculate the maximum lateness.

   Hint

   Order jobs by deadlines, then analyze finish times.

6. 6.

   You are given jobs with varying times and deadlines. How can you visualize the scheduling timings to assess maximum lateness effectively?

   Hint

   Focus on both finish points and deadline placements in your visualization.
