In this paper, Differential Evolution based approach with a novel dynamic constraint-handling mechanism is proposed to solve constrained real-parameter optimization. This is implemented by restating the single-objective constrained optimization as a set of single-objective unconstrained problems and dynamically assigning to the individual adaptively as its fitness. Three selection criteria based on...
A new language, Feldspar, is presented, enabling high-level and platform-independent description of digital signal processing (DSP) algorithms. Feldspar is a pure functional language embedded in Haskell. It offers a high-level dataflow style of programming, as well as a more mathematical style based on vector indices. The key to generating efficient code from such descriptions is a high-level optimization...
Statistical analysis of massive data is becoming indispensable to science, commerce, and society today. Such analysis requires efficient, flexible storage support and special optimization techniques. In this demo, we present RIOT (R with I/O Transparency), a system that extends R, a popular computing environment for statistical data analysis. RIOT makes R programs I/O-efficient in a way transparent...
There are increasing advances in learning technologies; by introducing learning concepts, platforms, e-learning technology standards, solutions and platforms. Since learning trends in the current time is focused on e-Learning due to globalization and internet, which is available for everyone, allot of developers passed over on developing classical learning technologies (.i.e. developing solutions...
The data structure diagram is abstracted from the diagram of railway yard signal arrangement. HBACA (hybrid behavior based ant colony algorithm) is presented to search the shortest route of railway yard. The route searching program based on HBACA is developed. The graphical representation of railway yard is given on the console. According to the designated beginning node and the designated ending...
The main idea of this article is through using Multi-level index and instruction abstract technology to improve the decode methods of the traditional MIPS instruction set simulation, The experiments show that this method can greatly improve the efficiency of program execution.
In the last few decades, many techniques have been proposed for the synthesis of large array antennas with simplified feed networks. In this framework of radar applications, the use of spatially contiguous sub-arrays of equal size allows the reduction of the number of antenna control elements, as well as to simplify the circuit complexity of the feed network. Despite the simplification of the antenna...
Compressing repeated instructions of the application program for mobile devices can significantly improve the performance and reduce the code size. The present work focuses on grouping of instructions based on data flow dependencies and repetition of operation code (Opcode). The compression is carried out by identifying the repeated sequences of instructions from the grouped Instruction Set (IS) and...
In this paper we investigate a self-adaptive differential evolution algorithm (jDEdynNP-F) where F and CR control parameters are self-adapted and a population size reduction method is used. Additionally the proposed jDEdynNP-F algorithm uses a mechanism for sign changing of F control parameter with some probability based on the fitness values of randomly chosen vectors, which are multiplied by the...
