Acceleration evolution in the distributed and cloud domains is common for large and dynamic workflows deployment. Resources and task mapping depend on the user’s objectives such as reduction in cost or execution completion within the stipulated time in consideration with certain quality of services. Multiple virtual machine instances can be launched by defining different configurations such as operating system, server types, and applications. Though workflow scheduling is an NP-Hard problem, variety of decision-making techniques are available for optimum resource allocation. In this research paper, different algorithms are studied and compared with evolutionary approaches. Workflow scheduling using genetic algorithm is implemented and discussed. This paper aims to design a decision-making technique to optimize resources of cloud. It is an adaptive scheduling to maximize profit by reducing execution time. The approach implemented is useful to cloud service providers to maximize profit and resource efficiency in their services.","PeriodicalId":256649,"journal":{"name":"Vietnam. J. Comput.

Currently, it is possible to find extreme ideologies regarding almost every topic such as religion, politics or sports. This problem, which ranges from personal identity conflicts to complex societal issues, has an impact on several people everyday, especially on youngsters. To confront this situation, the European Union found several initiatives, as a way to face this problem from a scientific perspective. Some of these initiatives face the problem trying to reduce radicalization by working on personal and social skills through education, in such a way the youngster’s resilience is improved. This paper aims to present YoungRes, a European project whose goal is to improve the resilience of youngsters. To do so, it unifies an already created intervention — named Fortius — through the inclusion of video games in the learning process. This paper describes both: (1) how the Fortius program is modified to allow video games sessions and (2) the software architecture designed to allow students and educators to participate in YoungRes project. Finally, different suggestions to include in future versions of the game are discussed.","PeriodicalId":256649,"journal":{"name":"Vietnam. J. Comput.

It is based on a Left-to-Right (LR) scanning process, which partitions the input stream into intervals. This task can be implemented by an algorithm or by using a generator that builds automatically the discretization program. We focus especially on unsupervised discretization and design a method called Usupervised Left to Right Discretization (ULR-Discr). Extensive experiments were conducted using various cut-point functions on small, large and medical public datasets. First, ULR-Discr variants under different statistics are compared between themselves with the aim at observing the impact of the cut-point functions on accuracy and runtime. Then the proposed method is compared to traditional and recent techniques for classification. The result is that the classification accuracy is highly improved when using our method for discretization.","PeriodicalId":256649,"journal":{"name":"Vietnam. J. Comput.

Traditional plant species identification is almost impossible for the general public and challenging even for professionals who deal with botanical problems daily such as conservationists, farmers, foresters, and landscape architects. Even for botanists themselves, species identification is often a difficult task. This paper proposes a model deep learning with a new architecture Convolutional Neural Network (CNN) for leaves classifier based on leaf pre-processing extract vein shape data replaced for the red channel of colors. This replacement improves the accuracy of the model significantly. This model experimented on collector leaves data set Flavia leaf data set and the Swedish leaf data set. The classification results indicate that the proposed CNN model is effective for leaf recognition with the best accuracy greater than 98.22%.","PeriodicalId":256649,"journal":{"name":"Vietnam. J.
