【Abstract】 A genetic algorithm of the Steiner tree problem is given. Accoroling to the character of the problem on the basis of introducing a new method with self-adaptive commute and mutate probability a new genetic algorithm for Steiner tree problem and a new method for constructing chromsome are presented. The structure of genetic algorithms is provided and its genetic algorithm operators are discussed. The complexity of algorithm based on time and space is analyzed.更多还原
