Expert Solution & Answer
Chapter 3, Problem 19PE
Explanation of Solution
Network diagram:
The network diagram for the activities:
Explanation of Solution
Earliest expected completion time:
- The earliest expected completion time is calculated by using time of each activity.
- The box in a network diagram represents the activity. Each box consists of activity and time.
- The start state is activity 1 and end state is 10. Each box consists of four values Early finish, Early start, Late start and Late finish.
- The early start for first activity is 0 because it contains no predecessor.
- Early finish is the sum of early start and time. Early start of the next activity is the early finish of its predecessor activity...
Explanation of Solution
Critical path:
- For calculating critical path, select all activities that contain slack value 0...
Explanation of Solution
Activity 6 revised to take 6 weeks:
- If the time of activity 6 is changed to 6 weeks instead of 2 weeks, then the critical will be changed...

After playing our giving implementation, your task is to implement Dinning Philosophers
with semaphore in C, by including and
Your implementation will require creating five philosophers, each identified by a number
0.4. Each philosopher will run as a separate thread. Create threads using Pthreads
as discussed in the Lecture slides on Chapter 4 and Practice Lab on Threads.
Your solution needs to accomplish the following:
Implement in C (15 points)
1. dp1.c - You are to provide your solution to this assignment as a single C program
named 'dp1.c using semaphore. Explain in you code (as comments) that the dead
lock will happen or not. If there is a possible deadlock, you can simply solve the
deadlock by pick the fork in order like the first solution in our slides.
Solve Deadlock by Footman (15 points)
