Multi-Objective Genetic Algorithm for Heston Model Calibration: A Framework Integrating Pricing and Implied Volatility Criteria

Accurate calibration of the Heston model is essential for reliable option pricing, yet it remains a challenging task due to the nonlinear structure of the model and the presence of multiple conflicting objectives. Most existing approaches rely on single-objective formulations that focus solely on price fitting, which m...
