Most of existing inlining algorithms are used in optimizing compilers and are not suitable for program analysis. Therefore, an inlining algorithm based on program dependence graph is proposed. It uses simple function call tree to determine the sequence of inlining and adopts program dependence graph as the intermediate representation for a program. Inline expansion is performed on program dependence...
The Smarandachely adjacent-vertex total chromatic number of graph G is the smallest positive integer k for which G has a proper total k-coloring such that for any pair of adjacent vertices u, v, the set of colors appearing at vertex u and its incident edges is not a subset of the set of colors appearing at vertex v and its incident edges. This paper,we obtain the Smarandachely adjacent-vertex total...
This paper presents a component-based model with a novel ranking method (CMR) for constrained evolutionary optimization. In general, many constraint-handling technique inevitably solve two important problems: (1) how to generate the feasible solutions, (2) how to direct the search to find the feasible optimal solution. For the first problem, this paper introduces a component-based model. The model...
There exist shortcomings of inaccuracy and subjective error in traditional manual core location. In order to overcome those disadvantages a new automatic method is proposed in this paper. There are relativities between the well logging curve and physical data at the same depth. Therefore the core location can be considered an optimization questions. Particle swarm optimization is a population-based...
We consider problems requiring to pack cylindrical objects into the cylindrical layout space by minimizing the static non-equilibrium quantity. So far there is few literature discussing the optimality conditions about layout problem. We present the main properties and the optimality conditions based on the three-dimensional layout optimization model with behavioral constraints. Moreover, we introduce...
This paper applies the principle of hierarchical coordination, fuzzy control theory and rolling horizon technique in coordinated control of urban trunk. The trunk control model includes two layers, manipulative layer and coordinated layer, controlled by different agents with different strategy. The paper gives detail description of coordinated layer control model, which applies fuzzy algorithm for...
Combining with genetic algorithm, the improved estimation of distribution algorithm (EDA) is provided. The crossover and mutation operations are added and the "elite" individuals are retained, which can keep the excellent evolution mode. The selection based on energy entropy is added, which can explore the solution space sufficiently and keep the population diversity. A neural network with...
In this paper, the necessary conditions for bilevel multiobjective programming problems are discussed. Assuming the upper-level objective functions in bilevel multiobjective programming problems are differentiable, we give and prove its first-order necessary conditions of the weak (strong) minimizer by applying the concept and properties of the contingent epiderivative for set-valued maps. The obtained...
In traditional simulation calculation of concrete filled steel tubular (CFST) arch bridge, to find out the initial state of the backward analysis is very difficult due to the force-bearing characteristics of CFST arch bridge. Genetic algorithm (GA), as a general-purposed global optimization algorithm, has the disadvantages of the premature phenomenon and poor performance in local optimization. In...
In this paper, we first describe the basic principle and the method of the A* algorithm. And we analyze the reason that the A* algorithm influences speed when it is searching for the optimum route in network game map. Then we give the optimization scheme from the aspects of node data structure to the maintenance of the open queue. At the same time, the optimization scheme is evaluated and tested by...
This separated cutting stock problem is a packaging of all rectangular pieces into a predefined size of material stocks using a minimum amount of these materials. It is similar to the trim-loss problem of subtracting the cost of a knife setup and adding the requirement of using the mini-mum number of material stocks. Current solving methods include the cutting stock problem, trim-loss problems, or...
Reconstructing meshes from 3D medical images is an important but complicated task, which provides a fundamental data structure for bio-medical applications. In this paper, a novel and easily implemental solution is proposed. Instead of following the popular methods, we sample on the medical images with centroidal Voronoi tessellations, and then build the Delaunay mesh from the sampled points directly...
This paper presents a fast stereo algorithm for obtaining disparity maps efficiently. We use a 3D model for storing and computing the depth map. The initial matching by intensity similarity is very fast by using the computational optimization. At the improving matching reliability step, two assumptions that were originally proposed by Marr and Poggio are adopted: uniqueness and continuity. It means...
Recent years have shown a surge in interest in fuzzy/temporal database systems, which allow users to store fuzzy time dependent information. Conventional relational systems are often inefficient for fuzzy temporal query processing because new characteristics are not taken into consideration. Representation and querying of temporal information can benefit from the integration of techniques from constraint...
In order to avoid the premature convergence and improve convergence rate, a novel adaptive genetic algorithm for reactive power optimization is discussed in detail. In reproduction operator, the method of retaining optimal individual is used to ensure the convergence and at the same time, the competition method is also adopted to keep the better dispersal of all individuals. In Mutation operator,...
Taking the example of traveling salesman problem, new heuristic strategy controlling the flight of partial dimensions in the swarm is put forward by analyzing the character existing in the edge-set intersection among particles, in order to resolve the problems of premature convergence and too-slow convergence existing in particle swarm optimization. The new strategy protects most edges belonging to...

For different closed circle DNA, the same position is corresponding to different recognition sequence, and the same recognition sequence is corresponding to different foreign DNA segment. Closed circle DNA algorithm of Hamilton circuit problem is put forward. In the algorithm, three groups of DNA encoding are encoded for all arcs, and deck groups...
Ant colony optimization (ACO) has the disadvantages such as easily relapsing into local optima and. Aimed at improving this problem existed in ACO, several new betterments are proposed and evaluated.

According to the importance position of form in product design, this research proposes a kansei-based method of product design to establish quantitative relationship between customers' feelings and product form features. Firstly, the form features of product are defined as evaluating attributes. Then through conjoint analysis, the utility value of each attribute can be derived for a given user image...
