**TLDR:** A method that searches for the best model by systematically trying predefined hyperparameter combinations.

<p>Grid Search is one of the most classical approaches to hyperparameter optimization. It evaluates all combinations within predefined parameter ranges and compares model performance across them. Its logic is clear and it can be effective in small search spaces. However, as the number of parameters grows, computational cost increases rapidly, making it inefficient in high-dimensional tuning problems.</p>
