Adaptive Firefly Algorithm

Definition

The Adaptive Firefly Algorithm is an optimization technique inspired by the behavior of fireflies, which use bioluminescent signals to attract mates and food. This algorithm adjusts its parameters dynamically during the optimization process to improve performance and enhance convergence speed, making it suitable for solving complex optimization problems.
