What is the goal of topological sorting?

The goal of a topological sort is given a list of items with dependencies, (ie. item 5 must be completed before item 3, etc.) to produce an ordering of the items that satisfies the given constraints. In order for the problem to be solvable, there can not be a cyclic set of constraints.

How many topological sorts are possible for the following directed graph?

Number of different topological orderings possible = 6. Thus, Correct answer is 6.

Can we apply topological sorting algorithm on the following graph?

Topological Sorting for a graph is not possible if the graph is not a DAG. For example, a topological sorting of the following graph is “5 4 2 3 1 0”. There can be more than one topological sorting for a graph. For example, another topological sorting of the following graph is “4 5 2 3 1 0”.

Which is not an application of topological sorting?

Which of the following is not an application of topological sorting? Explanation: Topological sort tells what task should be done before a task can be started. It also detects cycle in the graph which is why it is used in the Operating System to find the deadlock. Ordered statistics is an application of Heap sort.

Can we do topological sorting using BFS?

3 Answers. Yes, you can do topological sorting using BFS. Actually I remembered once my teacher told me that if the problem can be solved by BFS, never choose to solve it by DFS. Because the logic for BFS is simpler than DFS, most of the time you will always want a straightforward solution to a problem.

What is meant by topological sort specify its application with an example?

Topological sorting for Directed Acyclic Graph (DAG) is a linear ordering of vertices such that for every directed edge u v, vertex u comes before v in the ordering. For example, a topological sorting of the following graph is “5 4 2 3 1 0”. …

Which of the following is not an application of binary search?

Which of the following is not an application of binary search? Explanation: In Binary search, the elements in the list should be sorted. It is applicable only for ordered list. Hence Binary search in unordered list is not an application.

What will be the topological order when we apply the source removal based algorithm?

From a given graph find a vertex with no incoming edges. Delete it among with all the edges outgoing from it. If there are more than one such vertices then break the tie randomly. All these recorded vertices give a topologically sorted list.

What is topological sorting and what kind of useful information can we get from it what kind of data is it applied to?

In computer science, a topological sort or topological ordering of a directed graph is a linear ordering of its vertices such that for every directed edge uv from vertex u to vertex v, u comes before v in the ordering. Topological sorting has many applications especially in ranking problems such as feedback arc set.

What are the applications of binary search?

Applications of Binary Search

• This algorithm is used to search element in a given sorted array with more efficiency.
• It could also be used for few other additional operations like- to find the smallest element in the array or to find the largest element in the array.

What is topological sorting for a DAG?

Topological sorting for Directed Acyclic Graph (DAG) is a linear ordering of vertices such that for every directed edge u v, vertex u comes before v in the ordering. Topological Sorting for a graph is not possible if the graph is not a DAG.

What are the applications of topological sort in software development?

Some other applications of the topological sort are manufacturing workflows, data serialization, context-free grammar and many more. With this article at OpenGenus, you must have a strong idea of the applications of Topological Sort in real life problems and software systems.

What is topological sorting in graph theory?

Topological Sorting. Topological sorting for Directed Acyclic Graph (DAG) is a linear ordering of vertices such that for every directed edge uv, vertex u comes before v in the ordering. Topological Sorting for a graph is not possible if the graph is not a DAG. For example, a topological sorting of the following graph is “5 4 2 3 1 0”.

Are there any courses in topology in order?

There are some courses and they may have some prerequisite courses. One can finish courses in some order. Some other applications of the topological sort are manufacturing workflows, data serialization, context-free grammar and many more.
