An algorithm is a set of steps that must follow in order to solve a certain issue. In the field of computer science, there are a number of algorithms that fall into many categories. This blog is for you if you want to learn more about the many types of computer science algorithms used to accomplish tasks. Moreover, in this blog, we’ll go through the many algorithms you’ll need to know in 2022.
Advantages of computer science algorithms
- To make debugging an algorithm easier, each step has its own logical sequence.
- Also, it’s a visual depiction of a problem’s solutions that’s easy to learn.
- An algorithm serves as a blueprint for a program and supports its development.
- Also, the problem is broken down into smaller chunks or stages using an algorithm. This makes it easier for a programmer to translate it into a program.
- It’s simple to create an algorithm, then turn it into a flowchart, and finally into a computer program.
- A process is also used in an algorithm.
- It is not dependent on any programming language, so anyone can understand it, even if they have no prior programming experience.
How do you create computer science algorithms?
The following are the requirements for creating an algorithm.
- Conduct a detailed examination of the circumstances to define the issue.
- Constraints should be thoroughly examined.
- To write an algorithm, you’ll also need to input parameters.
- The problem’s expected outcome.
- The problem’s solution
List of computer science algorithms to learn
We do a lot of things in our everyday lives by following a set of steps.
This series of processes refers to as an algorithm. Learning algorithms allow you to use your coding abilities to solve real-world issues. And to do well in coding interviews. The following are also the computer science algorithms you should be aware of:
- Backtracking
- Graph
- Recursive
- Greedy
- Dynamic Programming
- Divide and Conquer
So these are the kinds of algorithms you’ll need to be familiar with. Let’s take a look at each algorithm one by one.
Backtracking algorithms
These are used to progressively describe a solution to a computational issue by solving a little section of it at a time. The algorithm iteratively also evaluates each alternative to pick the optimal solution for the problem. This is done each time it needs to choose between numerous alternatives for the next phase of the problem.
Moreover, these algorithms frequently use to make a series of decisions to construct a recursively specified structure. And all these meet particular conditions. Backtracking algorithms may also utilise in coding interviews in a variety of ways, including:
- Binary Search Trees
- Game trees
- Subset Sum
- N Queens problem
- Text Segmentation
Graph Algorithms
The related data is analyzed using graph algorithms. Graph algorithms’ mathematical computations depend on the understanding of data connections.
These algorithms also infer the architecture and behavior of complex systems based on the interactions between nodes. Network scientists use these algorithms in the real world to hide information and also anticipate behavior. Moreover, the following are some of the most commonly used graph algorithms:
- Dijkstra’s algorithm
- Prim’s algorithm
- Bellman-Ford algorithm
- Kruskal’s algorithm
- Breadth-first search
- Ford-Fulkerson algorithm
- Nearest Neighbor algorithm
- Depth-first search
Recursive Algorithms
These find in the notion of reductions, which refers to the process of reducing one issue A to another. Simply put, it also involves designing an algorithm for A that uses a subroutine from an algorithm for B. Thus, if a particular example of a problem can solve directly, recursive algorithms can solve it directly or reduce it to one or simpler examples of the same issue. Here are a few instances of recursive algorithms in action:
- Fibonacci Series
- Sorting a number array or list
- Calculating the addition of the number array
- Calculating Factorials
Greedy algorithms
These computer science algorithms find the best answer from all available options while solving a problem, depending on the problem. It also creates an object that takes one step at a time. Moreover, it allows the user to select the best alternative at each stage. This is why the technique’s name is “greedy.” It also frames a solution by selecting the best feasible answer to the problem. Here are a few greedy algorithm examples:
- Traveling Salesman problem
- Dijkstra’s Minimal Spanning Tree
- Prim’s Minimal Spanning Tree
- Kruskal’s Minimal Spanning Tree
Dynamic programming
The notion of dynamic programming is commonly employed in optimization. This is a recursive method of breaking down a complex problem into smaller subproblems. An issue must also have two crucial characteristics to be solved using dynamic programming:
- Substructure that is optimal.
- Subproblems that overlap.
The concept behind utilising dynamic programming to solve an issue is to break down a complicated problem into multiple basic problems.
Divide and conquer algorithms
These computer science algorithms are used to solve problems by:
- breaking the problem into subproblems, which are also smaller versions of the same problem,
- Also recursively solving the problem,
- and then merge the answers to all the subproblems to get a final solution.
The following are some examples of popular algorithms based on the divide and conquer strategy:
- Merge Sort
- QuickSort
Let’s wrap it up!
So these are the algorithms you should be familiar with while diving into challenges involving data structures and computer science algorithms. Moreover, learning algorithms allow you to use your coding abilities to solve real-world issues. And also do well in coding interviews.
