Solving JSSP is an intractable subject. It has great significance in improving productive efficiencies for manufacture enterprise. In recent decades, designing algorithms for solving problem of JSSP problem become an important issue. Moreover, it is difficult to find an appropriate criteria to evaluate efficiency of algorithms available with respect to solving JSSP. Various algorithms for solving...
In the recent years, Internet has witnessed a rapid growth in the deployment of data-driven based peer-to-peer streaming systems. The power of such system arises from the altruism of participating nodes in the system. However, as the system grows larger, the assumption of altruism breaks down since the system may include selfish nodes, which consume the resources provided by other nodes, without contributing...
despite the fact that mobile video application is gaining tremendous popularity amongst mobile users across the globe, mobile users can hardly get access to video with high quality mostly because decoding high resolution video is so time-consuming that CPUs of mobile device can't cope with it. In this article, we optimize H.264 decoding with ARMv7 assembly on mobile phones running on Android. Experiments...
With the rapid development of information technology, search engine optimization (SEO) technology has attracted more and more attentions. In order to improve their website visit quantity, SEO techniques can make a better ranking in the search result using the keyword selection and deployment, high quality back links, rational website constitution, and rich content, etc. This paper discusses in detail...
The selection strategy of overlay link directly affects the performance of overlay network routing, and another important factor that can affect the performance of overlay network is that the overlay link has an exorbitant level of reuse with the physical link, but they are not much considered in previous studies. Taking full account of various factors that can affect the performance of overlay network...
Based on GPRS Time Based Charging Gateway (TBCG) in one communication operator, the Paper analyses processing bottleneck of this module. It caused system inefficient and inconsistency of the user order data between TBCG and BOSS (Business Operation Support System). On the basis of current GPRS Charge Detail Record (CDR) processing procedure in the BOSS, it adds a new CDR processing module of GPRS...
In this paper the motion equation of the submarine is simplified, the sliding mode tracking controller of direction is designed to reduce the effects of strongly-coupled and nonlinear equation itself, and it is optimized via genetic algorithms to determine the optimal parameters of the controller, The effectiveness of the optimized sliding mode controller is demonstrated through the simulation results...
A novel cutting plane algorithm for integer linear programming (ILP) is proposed in this paper. It restarts with an all-integer ILP system at each iteration by adding an all-integer cut, which is the function of the non-basis variables of the original system, to original system. Compared with fractional cutting plane (FCP) algorithm, this algorithm shows favorable numerical stability. Compared with...
The peak-valley time of use (TOU) power price is an effective demand side management measure which affects the power consumption way of the end-users via price mechanism. With the help of the peak-valley power price policy, an enterprise working time optimization and benefit analysis simulation system is designed and realized, which can guide the industrial users to optimize and adjust the work time...
The Parallel Ocean Program (POP), one of the ocean general circulation models (OGCMS), is widely used in ocean and climate research. This paper presents the SIMD optimization performance of POP on the Intel Xeon X86_64 platform based on the Intel FORTRAN compiler. The results show that SIMD can improve the computation speed of POP, whether high or low resolutions. In the low resolution, the speedup...
It is proper that to evaluate algorithm's performance using statistics for stochastic search optimization such as PSO. In this paper, we do performance statistics and analysis for some different situation taking Rosen Brock function as example, from statistics we think that local model is better than global model in avoiding premature, and neighborhood size is not important, number of particles should...
This paper deals with the ADRC controller design. Aiming at its three main parameters related to interference rejection, a PSO algorithm-based on-line optimization method is proposed. In order to raise the efficiency of on-line optimization, two improvements are applied in the PSO algorithm, one is using the threshold of system error to trigger the PSO algorithm, and the other is using the Pareto...
This paper presents an improved differential evolution based on Gaussian disturbance for multi-objective optimization. Differential evolution algorithm is often trapped in local optima and converges slowly. In this paper, Gaussian disturbance is employed to increase the variety of the individual to improve its performance. External archive is employed to reserve the non-dominated solutions and crowding-distance...
The difference between interactive evolution-ary computation (IEC) and traditional evolutionary computation (TEC) is that in IEC individuals' fitness is subjectively assigned by the user, while in TEC the fitness is objectively given by function or others. The user in IEC assigns fitness according to his/her preference. Therefore, if his/her preference drifts, the implicit fitness function for preference...
This paper presents a few design considerations in implementing building block-based Computer Aided Design (CAD) for analog switched circuits. The considered synthesis include four independent levels: 1) system level, 2) building block level, 3) circuit simulation level, and 4) layout generation, which multistage can separate a larger size circuit into a few major basic building blocks. The aim of...
