Imagine you have a recipe for making a chocolate cake. This recipe tells you exactly what ingredients you need, what to do with them, and in what order. In the world of computers, algorithms are like these recipes. They give computers a set of steps to follow so they can do tasks or solve puzzles. Algorithms are super important for everything computers do, from helping your video game run smoothly to making smart robots think and make decisions. They turn big, tricky problems into easy steps that computers can follow quickly and perfectly, doing things much faster than people can. Just like how you might follow a simple recipe to make a sandwich or a more complex one for a big holiday dinner, there are all kinds of algorithms. Some are simple and do basic things, and some are really smart and help with big decisions, like how a self-driving car knows where to go. Keep Reading more about What is Algorithm!What is Algorithm?

This ensemble method improves upon decision trees by creating a ‘forest’ of trees and merging their predictions, which enhances the overall accuracy and reduces the risk of overfitting.
Gradient Boosting Machines (GBM):
GBMs sequentially construct new models to correct errors made by previous ones, effectively improving performance with each step and tackling a wide range of regression and classification problems.
How Do Algorithms Work?
At their core, algorithms are about taking inputs, performing a series of defined steps, and producing outputs. This process involves basic components that are common across all types of algorithms.
Input:
Every algorithm starts with input, which can range from simple numerical values to complex datasets. The input is the information that needs to be processed or the problem that needs to be solved.
Processing:
This is the heart of the algorithm, where the actual computation or logic is applied. It involves a sequence of steps or rules that transform the input into the desired outcome.
Output:
The output is the end result produced by the algorithm. It could be a simple answer, like the sum of two numbers, or a more complex result, like a predictive model or a sorted list.
Types of Algorithms
Now let’s discuss five basic types of algorithms:
Machine Learning Algorithms:
These are designed to learn from data, adapt their parameters, and improve their performance over time without being explicitly programmed for specific tasks.
Search Algorithms:
These algorithms navigate through data structures to find specific elements or paths between elements, crucial for tasks like database searches and pathfinding in maps.
Sorting Algorithms:
Sorting algorithms organize data into a predetermined order, facilitating easier data analysis and retrieval. Common examples include quicksort, mergesort, and bubblesort.
Graph Algorithms:
These algorithms are used to solve problems related to graphs and networks, such as finding the shortest path between nodes, which is essential for routing and network analysis.
Dynamic Programming Algorithms:
By breaking down problems into simpler sub-problems, dynamic programming algorithms efficiently solve complex problems, often used in optimization and sequence alignment tasks.
