Algorithm - Explanation, Usage, and Effectiveness

An algorithm is a structured set of individual steps that define the exact sequence of actions to be performed. It can be described as a series of written instructions used to achieve a specific goal or solve a complex problem.

Algorithm as a System of Commands

In the fields of mathematics, computer science, and biological neural networks, algorithms play a crucial role. In computer science, an algorithm is a precise set of instructions that ensures the correct functioning of a program when performing various tasks.

An algorithm can be considered as a performer of simple operations—such as subtracting two numbers—as well as more complex calculations, for example, determining the optimal direction between two or more geographic points. Computer algorithms help us do everything—from calculations and data analysis to obtaining other insights.

Standards for Evaluating Algorithms

Every algorithm has a fixed starting and ending point—based on the input information and pre-planned steps, the results are derived. For complex problems, a combination of several algorithms is often used, but increased complexity requires more computational resources.

Algorithms are evaluated based on their accuracy and efficiency. Accuracy measures how precise the algorithm is and whether it can adequately solve a particular problem. Efficiency, in turn, relates to the amount of resources and time required to solve a specific task. Computer science specialists use well-known asymptotic analysis methods to compare different algorithms—this mathematical technique objectively assesses algorithms regardless of the programming language or specific hardware used.

Bitcoin and Proof of Work: An Algorithm in Practice

In the blockchain ecosystem, Bitcoin uses one of the most important algorithms—Proof of Work—which is fundamental to the mining process. This algorithm performs operations that verify and confirm transactions, ensuring the security of the blockchain network and its proper functioning.

Proof of Work means that miners must solve a complex mathematical problem before adding a new block to the chain, which is carried out through a process that consumes time and energy resources. This algorithm helps maintain the security of the network and prevents malicious activities.
