Inverse treatment planning for radiation therapy is a multi-objective optimization process.The hybrid multi-objective optimization algorithm is studied by combining the simulated annealing(SA) and genetic algorithm(GA).Test functions are used to analyze the efficiency of algorithms.The hybrid multi-objective optimization SA algorithm
which displacement is based on the evolutionary strategy of GA: crossover and mutation
is implemented in inverse planning of external beam radiation therapy by using two kinds of objective functions
namely the average dose distribution based and the hybrid dose-volume constraints based objective functions.The test calculations demonstrate that excellent converge speed can be achieved.
