With the application of global optimization algorithm, the research of parallel optimization algorithm and its realization become very important. In this paper, two kinds of parallel models of parallel integer coded differential evolution strategy, such as master-slave model, coarse-grained model, are proposed and simply evaluated. For engineering problems, the integer coding is efficient, and automatically...
We combined a cylinder with deformation and accomplished the visualization for creating animation of the growth of fruit from opening flower to yield fruit. The beginning model is a cylinder that simulate plant stem, and adds perturbation function to the cylinder surface in the direction of the unit surface normal. We may distort a cylinder to the geometry shape of flower and fruit. The perturbation...
In this paper, it is given a new method of solving the fuzzy linear programming-the basic line algorithm. Compared with the simplex method in solving the fuzzy linear programming currently, the basic line algorithm not only has its advantages on both data stability and anti-cycle and so on, but also shows superior on reducing the solving steps and having no need to calculate the checking figures....
Parallel computation technique is an effective way to solve large-scale electromagnetic problems. This paper writes the program of parallel FDTD based on the JASMIN framework. The parallel FDTD program was used for simulating the time-domain far field property of the electric dipole source and a single TEM horn antenna. Numerical results show that the program is correct and efficient. Two large-scale...
An algorithm of fractal tree is hot research area in nature scenery simulation. We present a generate algorithm of fractal tree by use a controllable random transform method. This method base on fractal theory, controls some parameters of fractal tree generating in a random scope, which parameters including coordinates, length of tree branch, angle of tree branch transfer, thickness of trunk, color...
We propose a simple and effective modeling method for creating animation opening flowers. Because the detailed geometry of flower petals is defined by a base shape deformation, we simulate the development of petal based on deformation and emulate its growth by change the deformation parameters. The structural arrangement of flower petals is established by the L-system that produces natural looking...
