After introducing the suitable merit function,a broad angular broadband W/B_4C multilayer film has been designed successfully by using genetic algorithm.

And it can decrease the value of the merit function by inserting new thin layer.

The method is a very fast and stable refinement technique that makes for the nearest merit function minimum, and it is particularly suitable for the adjustment of an already useful design.

Several extrema may be produced in evaluating function curves,as image noise is caused by interferences in image gathering,quantifying and transmission processes.

To overcome the difficulty of generating larger dithering pattern based on evaluating function, we proposed the strategy of partitioning the initial pattern, and progressively enlarging the dithering pattern.

One of the key technology for outdoor mobile robot is the optimal control of the high speed wheeled mobile robot, This article deals with the evaluating functions and methods of their solutions in detail, started by analyzing dynamics models of vehicle and typical modes of roads.

So a genetic algorithm(GA) optimization technique is applied to multilevel inverter to determine optimum switching angles for cascaded multilevel inverters for minimizing some predominant lower order harmonics via a cost function while maintaining the required fundamental voltage.

In this paper,we reconstruct a cost function based on second order statistics.

The algorithm could construct and use different cost functions for the circuit modules with and without fast carry chain.
