In order to solve the problem of slow convergence speed of adaptive genetic algorithm (AGA) in the early stage of evolution, an improved adaptive genetic algorithm (IAGA) was presented. With the introduction of an indicator evaluating the degree of population diversity, the new algorithm can adaptively adjust the probabilities of crossover. Furthermore, the IAGA was applied to vehicle routing problem...
Crossover operation is the main means of Genetic Algorithms, for the lack of crossover operation, from three aspects of crossover operation, systemically proposed one kind of improved Crossover operation of Genetic Algorithms, namely used a kind of new consistent Crossover Operator and determined which two individuals to be paired for crossover based on relevance index, which can enhance the algorithm's...
Operation in a container terminal is a complex system with many inter-related decisions. In this paper, a bi-level programming model for container terminal scheduling is developed to improve the integration efficiency of container terminals. The model consists of two sub-models, the upper-level model is quay crane scheduling problem, and the lower-level one is dynamic trailer routing problem. The...
