Immune Genetic Algorithm-based Load Balancing (IGALB) was proposed to improve the efficiency of search quality and the poor performance of local search in the Simple Genetic Algorithm-based Load Balancing (SGALB). This algorithm ensured the diversity of population and overcame the SGALB premature convergence by carrying out the affinity and concentration calculations. Meanwhile under certain conditions...
We present a new algorithm for exact multiple string matching. Our algorithm is based on filtration combining BNDM and q-grams. We have tested it with experiments and compared it with other algorithms, e.g. DFA, AC_BM and MWM. The preprocessing phase of our algorithms is fast, the memory usage is fairly small, and our algorithm is considerably faster for huge sets of several thousand patterns. The...
Resource discovery is an important aspect of computational Grid. Locating resources in a Grid environment is difficult because of the geographic dispersion and dynamic nature of its resources. In this paper, a center-distributed virtual community model is designed. Based on his model, a novel grid resource discovery method is presented. Its simulation experiment shows the present algorithm can solve...
Borrowing ideas from one-dimensional array selection sorting algorithms, we propose a sorting algorithm for two-dimensional arrays. Both theoretical analysis and experimental evaluation show that the proposed algorithm is easy to implement, and has much lower computational complexity than one-dimensional sorting algorithms, especially when arrays have large size. Furthermore, we convert the sorting...
Since the multi-innovation stochastic gradient (MISG) method can produce highly accurate parameter estimates for linear regression models, this paper extends the MISG method to nonlinear regression models and presents an MISG algorithm for Hammerstein nonlinear CAR (ARX) systems with memory less nonlinear blocks followed by controlled autoregressive models. The numerical results indicate that the...
