A computational model is a mathematical model that requires a computer to solve or simulate its processes. It employs algorithms and data structures to represent complex real-world systems, phenomena, or abstract concepts, allowing researchers and engineers to study their behavior without direct physical experimentation.
These models are built upon a framework of equations, logical rules, and parameters derived from scientific theories, empirical observations, or existing data. The core principle is abstraction, simplifying complex realities into a tractable form to make the simulation and analysis computationally feasible.
For instance, meteorologists use computational models to predict weather patterns by simulating atmospheric dynamics. Engineers apply them to design stress-resistant structures or optimize aerodynamic shapes. In biology, models can simulate population growth or the spread of diseases, while in finance, they predict market trends.
Computational models are indispensable tools for making predictions, understanding complex interactions, and testing hypotheses across various STEM disciplines. They enable the exploration of scenarios that are too expensive, dangerous, or impossible to reproduce in a laboratory, accelerating discovery and innovation.
