The search algorithm of the steepest direction is proposed to solve the optimization problem that the objective function is complex and the derivative is hard or impossible to obtain
The algorithm doesn’t need to obtain the derivative in its searching process
overcoming the weakness of needing to acquire the derivative during their searching process
which some other local search algorithms have. A hybrid genetic algorithm
based on the search algorithm of the steepest direction
is proposed. The algorithm combines the search algorithm of the steepest direction with the genetic algorithm effectively
enhancing the searching ability of the genetic algorithm. The experimental results show that the improved genetic algorithm is more effective than some current optimization algorithms.
