    ABSTRACT: This paper considers the impact of the distance from cluster heads (CHs) to the sink, and uses evolution game-theoretic model to analyze the communication energy optimization. We present the area division scheme of sensors so as to achieve a desirable communication energy optimization. By analyzing the evolution stable strategy (ESS) of territory game model, we propose a clustering algorithm based on territory game (TGC algorithm) to define the area limits. TGC algorithm mitigates the unbalanced energy consumption caused by the asymmetrical distance from CHs to the sink. By analyzing the ESS of the war of attrition game, we propose a clustering algorithm based on the war of energy attrition (WEAC algorithm). WEAC algorithm selects CHs from low energy sensors only considering individual remaining energy rather than the distance from their CHs to the sink. Simulations are given to validate the proposed TGC and WEAC algorithms. The results show the proposed algorithms achieve desirable network performances.

    ABSTRACT: Based on a simple transformation, and with the aid of symbolic computation, a Bäcklund transformation relating the Jimbo–Miwa equation and a system of linear partial differential equations is obtained, which enables us to construct exact solutions of the Jimbo–Miwa equation through the Wronskian determinants of independent solutions of the linear system. Particularly, explicit Wronskian form NN-soliton solutions for the Jimbo–Miwa equation are presented. Moreover, the introduced transformation also helps to construct bi-soliton-like solutions of the Jimbo–Miwa equation. Due to the arbitrary functions they contain, the bi-soliton-like solutions can represent various waves such as classical cross-line bi-solitons, curved bi-solitons and bi-soliton-like breathers.

    ABSTRACT: This paper presents an efficient algorithm, called dynamic fuzzy cluster (DFC), for dynamically clustering time series by introducing the definition of key point and improving FCM algorithm. The proposed algorithm works by determining those time series whose class labels are vague and further partitions them into different clusters over time. The main advantage of this approach compared with other existing algorithms is that the property of some time series belonging to different clusters over time can be partially revealed. Results from simulation-based experiments on geographical data demonstrate the excellent performance and the desired results have been obtained. The proposed algorithm can be applied to solve other clustering problems in data mining.

    ABSTRACT: A novel cluster validity index whose implementation is based on the membership degrees and improved bipartite modularity of bipartite network is proposed for the validation of partitions produced by the fuzzy c-means (FCM) algorithm. FCM algorithm is employed to group the dataset in order to obtain the membership degree of samples. Then, a weighted bipartite network is constructed by samples and centroids of each cluster. This allows the introduction of a new measurement for optimizing the numbers of clusters for fuzzy partitions. The proposed index utilizes the optimum membership as its global property and the modularity of bipartite network as its local independent property. The proposed index is compared with a number of popular validation indices on fifteen datasets. The experimental results show that the effectiveness and reliability of the proposal is superior to other indices.

    ABSTRACT: The aim of this paper is to detect communities in complex networks. A density set algorithm (DSA) is proposed by introducing the concept of density set. The key idea of the algorithm is to constantly construct density sets in a network and decide whether the density set constructed later can lead to generate a new community or amalgamate it with an old one. Step by step, the networks with apparent community structure can be partitioned well by the proposed method. The running time of DSA is approximately O(n+m) for a general network and O(n) for a sparse network, where n is the number of nodes and m the number of edges in a network. Tests on three typical real-world networks and a benchmark reveal that DSA produces the desired results. So the proposal is reasonable and has the potential for wide applications in physics and computer science.

    ABSTRACT: This paper presents a fuzzy support vector classifier by integrating modified fuzzy c-means clustering based on Mahalanobis distance into fuzzy support vector data description. The proposed algorithm can be used to deal with the outlier sensitivity problem in traditional multi-class classification problems. The modified fuzzy c-means clustering algorithm based on Mahalanobis distance takes into the samples’ correlation account, and is improved to generate different weight values for main training data points and outliers according to their relative importance in the training data. Experimental results show that the proposed method can reduce the effect of outliers and give high classification accuracy.

    ABSTRACT: By analyzing the characteristics and disadvantages of existing keyword extraction algorithms based on a complex network, a new keyword extraction algorithm is proposed by using a weighted complex network. First of all, the weighted complex network model is constructed according to the relationship among the words of a text. Secondly, a weighted clustering coefficient and betweenness are introduced to calculate a node’s multi-feature value. Finally, the keywords are extracted using the multi-feature values. Experimental results show that the keywords extracted by this algorithm are in good agreement to a text’s subject, and the accuracy of the keyword extraction is better than for the existing algorithms.

    ABSTRACT: A snowball algorithm is proposed to find community structures in complex networks by introducing the definition of community core and some quantitative conditions. A community core is first constructed, and then its neighbors, satisfying the quantitative conditions, will be tied to this core until no node can be added. Subsequently, one by one, all communities in the network are obtained by repeating this process. The use of the local information in the proposed algorithm directly leads to the reduction of complexity. The algorithm runs in O(n+m) time for a general network and O(n) for a sparse network, where n is the number of vertices and m is the number of edges in a network. The algorithm fast produces the desired results when applied to search for communities in a benchmark and five classical real-world networks, which are widely used to test algorithms of community detection in the complex network. Furthermore, unlike existing methods, neither global modularity nor local modularity is utilized in the proposal. By converting the considered problem into a graph, the proposed algorithm can also be applied to solve other cluster problems in data mining.

    ABSTRACT: In this paper, to understand the role of nonlinear dispersion in the coupled systems, the nonlinear dispersion Drinfel’d–Sokolov system (called D(m,n) system) is investigated. As a consequence, many types of compacton and solitary pattern solutions are obtained. Moreover, some solitary wave solutions are also deduced for differential parameters m, n. When n=1, the D(m,1) system with linear dispersion is shown to possess also compacton and solitary pattern solutions, which contain the known results. Moreover, some rational solutions of D(m,n) system are also deduced.

    ABSTRACT: Many networks of interest in the science, including social networks, computer networks and the World Wide Web, are found to be divided naturally into communities or groups. The problem of detecting communities is one of the outstanding issues in the study of network systems. Based on the improved shared nearest neighbor (SNN) similarity matrix, spectral method and fuzzy c-means (FCM) clustering algorithm, this paper proposes a new algorithm for detecting the communities in complex networks. The experiment reveals the validity of the presented method. The results are compared with other ones obtained by the different existing well methods and the conclusion is that the accuracy of the results calculated by this approach is much better than the known ones.

    ABSTRACT: A method is proposed to construct closed-form solutions of nonlinear differential-difference equations. For the variety of nonlinearities, this method only deals with such equations which are written in polynomials in function and its derivative. Some closed-form solutions of Hybrid lattice, Discrete mKdV lattice, and modified Volterra lattice are obtained by using the proposed method. The travelling wave solutions of nonlinear differential-difference equations in polynomial in function tanh are included in these solutions. This implies that the proposed method is more powerful than the one introduced by Baldwin et al. The results obtained in this paper show the validity of the proposal.
