Optimality vs Completeness: Striking a Balance in Algorithm Design

In computer science, algorithms are essential tools for solving problems efficiently. When designing algorithms, two key concepts to consider are optimality and complexity. Both concepts are related to the efficiency of an algorithm, but they approach efficiency from different perspectives. Optimality refers to the best possible solution to a problem,...

Matrix Factorization

Matrix factorization is an essential technique in linear algebra, which involves decomposing a given matrix into the product of two or more matrices. This technique has numerous applications across various fields, including data analysis, signal processing, machine learning, and computer graphics. Matrix factorization can be understood as a process of...

Candle Alarm Clocks

Before the invention of the clock, people relied on various methods to measure time. One of the most common tools used in the past was the alarm candle, a special type of candle designed to burn for a set amount of time before extinguishing itself, thus signalling the passage of...

Taylor’s Series Theorem

Taylor’s series theorem is a powerful mathematical tool that allows us to represent many different functions as an infinite sum of simpler functions. This theorem has many practical applications in science, engineering, and finance, among other fields. The theorem is named after the British mathematician Brook Taylor, who first discovered...
