We model document summarization as a nonlinear 0-1 programming problem where an objective function is defined as Heronian mean of the objective functions enforcing the coverage and diversity. The proposed model implemented on a multi-document summarization task. Experiments on DUC2001 and DUC2002 datasets showed that the proposed model outperforms the other summarization methods.

The number of complete chloroplastic genomes increases day after day, making it possible to rethink plants phylogeny at the biomolecular era. Given a set of close plants sharing in the order of one hundred of core chloroplastic genes, this article focuses on how to extract the largest subset of sequences in order to obtain the most supported species tree. Due to computational complexity, a disc...

In intelligent watermarking (IW), evolutionary computing (EC) is employed in order to automatically set the embedding parameters of digital watermarking systems for each image. However, the computational complexity of EC techniques makes IW unfeasible for large scale applications involving heterogeneous images. In this paper, we propose a dynamic particle swarm optimization (DPSO) technique whi...

Most of the existing IDS use all the features in network packet to evaluate and look for known intrusion patterns. This data contains irrelevant and redundant features. Unfortunately, the drawback to this approach is a lengthy detection process. In real-time environment this may degrade the performance of an IDS. Thus, feature selection is required to address this issue. In this paper, we use w...

Abstract Lung infection or sickness is one of the most common acute ailments in humans. Pneumonia lung infections, and annual global mortality rate from untreated pneumonia increasing. Because its rapid spread, caused by Coronavirus Disease (COVID-19) has emerged as a danger December 2019. At clinical level, COVID-19 frequently measured using Computed Tomography Scan Slice (CTS) Chest X-ray. Th...

This paper proposes an approach for web services composition based on domain ontology and discrete particle swarm optimization (DPSO) algorithm. This method builds an optimized graph for service composition based on domain ontology and its reasoning capability, and then a discrete particle swarm optimization algorithm based on the graph is proposed to accomplish service composition. The simulat...

Image segmentation has been widely used in document image analysis for extraction of printed characters, map processing in order to find lines, legends, and characters, topological features extraction for extraction of geographical information, and quality inspection of materials where defective parts must be delineated among many other applications. In image analysis, the efficient segmentatio...
