Mathematical Modeling

Definition

Mathematical modeling is the process of representing real-world systems or phenomena using mathematical concepts and language. This involves creating equations or algorithms that describe the behavior of a system, which can then be analyzed and solved to gain insights into the underlying processes. In the context of systems biology, mathematical modeling helps researchers understand complex biological interactions and predict how systems will respond to various stimuli.
