Fast algorithm for path planning is helpful for artificial intelligence. Genetic Algorithm (GA) is a typical evolution method, used widely in path planning. A new GA based on path network is proposed in this paper. Efficient chromosome encoding strategy provided guarantees, and each chromosome represents a feasible path, avoiding the searching circulation. Variation happens at certain positions, making...
Based on the traditional theory and algorithms of vehicle routing problem, the multi-objective VRPSDP mathematical model is established in considering the minimum of the number of vehicles and the transportation costs. The genetic algorithm is used as the solving algorithm of the model in this paper, in order to ensure the effectiveness of the chromosomes in the iterative process, the chromosome encoding...
This paper proposes a fast macro block selection algorithm using Haar wavelet features for H.264/AVC video codec system. The proposed algorithm makes use of the two-dimensional Haar wavelet transform to estimate the sub-band energy of each macro-block in a given video frame. Then the sub-band energy can be applied to the macro-block mode decision as a primary parameter. To prevent the error segmentation,...
To solve the security problem of multi-media, data hiding is one of important technologies. Loss less data hiding is a special type of data hiding technologies with the characteristic of completely recovering the cover media after the embedded data are extracted. Recently, many reversible data hiding methods have been proposed for VQ-compressed images. Lu et al. proposed a VQ reversible data hiding...
In this study, the genetic algorithms and fuzzy comprehensive evaluation were used together to analyze the product assessment data. It is explored which operators were employed and whether everybody used the same operators in fuzzy comprehensive evaluation. It investigated the evaluation made by undergraduates on Master Kong beef instant noodle. The results demonstrated that males used the “max...
In order to determine the optimal set of maintenance strategies for a network of bridges with concrete decks, a maintenance strategy optimization method using interactive genetic algorithm is presented in this paper. Evolution is leaded into optimal comprehensive performance of multiple objects by way of inputting inaccurate preference information and fitness Sharing technique is introduced to improve...
With the development of technology, calculated amount especially in seismic data processing is increasing in virtual computing environment and the data size is astonishing. In this paper, based on the seismic data and the influence factors during the calculation, we present a suitable data partitioning strategy-the PGA (Pretreatment Genetic Algorithm) algorithm. The scheduling problem in virtual computing...
In the daily life, secret data delivery is an important application for privately communicated to each other over computer networks. Data hiding technique is a good way to achieve the secret data delivery, thus the color image is a popular cover media used to send the secret. Block truncation coding (BTC) is a lossy image compression technique, which can significantly reduce the size of image. In...
