Question

The graph below describes the dependences between tasks that processor. Note that we areconcerned time, need to be scheduled on a single with start time, finish times, deadlines, nor penalties For example, Task 1 must run and complete before Task 3 cn and 6 must complete before Task 5 can start be executed Sielarly, Tads . Describe an algorithm that can be used to will be executed and no dependencies will be determine a schedule of the tasks so that all violated b. Apply it to the cxample to the left. e. What is the time complexity of your approach? Version D

Explanation / Answer

a)

We will use topological sort algorithm with DFS traversal.

b) Topological sort

c) Topological sort is basically a DFS with extra space(equivalent to number of vertices).

Time Complexity O(V+E)
