Abstract
We propose a hybrid algorithm based on genetic algorithm (GA) and ant colony optimization (ACO) for optical focusing inside/through scattering media. The hybrid algorithm has the basic structure of a GA, where the offspring generation procedures (i.e., parent selection and crossover) are replaced by the path generation procedures in ACO. The GA-ACO is advantageous by the rapid discovery of good solutions from ACO and enhanced solution diversity from GA. Therefore, the algorithm has a strong ability to search for a global optimal solution quickly, and experimentally we can achieve optimization results approaching the theoretical optimum.
