Constructing low cost software is the main method to save energy source in computer science. Traditional research about software cost is only in one level. They are partial in some degree. To settle the problem
a systemic model for software cost analyzing and optimizing is proposed in this paper. In this systemic model
software cost analyzing and optimizing are from low level to high level. It can provide all-sided analyzing and optimizing in instruction
source code level and structure level. Some suggestions and methods are given in each level to enrich the model. The systemic model expresses a new point of view in software cost. 2011 IEEE.

In order to meet the requirement of inertial navigation components and minimizing the system's weight
and topological optimization was conducted. Then
topological optimization and size optimization were conducted under conditions of random vibration and impact. Firstly
according to the dynamic characteristics of missile and requirement of inertial navigation system
the structure of inertial navigation support was designed according to types of missile connection and space arrangement of electronic components
the method of transforming multi-loading cases to multi-loading constraints was used to optimizing the size of the support under conditions of random vibration and impact. Comparing to the original support structures
RMS accelerations in installed points reduced by 25.2% under random vibration
the weight of optimal structures reduced by 28.1%
the structures also met the requirement of inertial navigation system under condition of impact. The support structure shows improvements in both dynamic characteristic and light weight comparing with the original one. 2011 IEEE.

In feature-level fusion recognition system
the other is optimizing system sensor design to get outstanding cost performance. So feature selection become usually necessary to reduce dimensionality of the combination of multi-sensor features and improve system performance in system design. In general
there are two main missions. One is improving the recognition correct rate as soon as possible
the optimization is usually applied to feature selection because of its computational feasibility and validity. For further improving recognition accuracy and reducing selected feature dimensions
this paper presents a more rational and accurate optimization
Bidirectional Binary Particle Swarm Optimization (BBPSO) algorithm for feature selection in feature-level fusion target recognition system. In addition
we introduce a new evaluating function as criterion function in BBPSO feature selection method. At the last
we utilized Leave-One-Out method to validate the proposed method. The experiment results show that the proposed algorithm improves classification accuracy by two percentage points
while the selected feature dimensions are less one dimension than original Particle Swarm Optimization approach with 16 original feature dimensions. 2009 IEEE.

In Computer Controlled Optical Surfacing (CCOS)
polishing tool-path is the base of solving other control parameters such as dwell time. In order to improve the fabrication results of polishing off-axis aspheric
a novel method to optimize the tool-path is discussed in this paper. The optimizing method named weighted-iterative algorithm is according to the balance principle of the particle system. The power factor of each dwell point represents the requirement of dwell density. Considering the factors which influence the polishing result
the power factors cosist of three elements include constant
error distribution and dwell distance of workpiece edge. The tool-path is solved by numerical iterative method. In the end
an error data is simulated with actual parameters using the matrix-based algorithm with two different tool-paths. The one is X-Y uniform spacing model and the other one is to optimize it based on the first. The comparison shows that the results of the optimized one are much better than traditional one
especially the rms convergence rate. Theory of the algorithm is simple and exercisable
and it satisfies practical requirement as well. 2009 SPIE.

Optimizing the control mode of optical payload could improve the payload's work efficiency. When the mathematic model of payload's control mode was established
optimization problems could be boiled down to seek the maximal value of the function with many variables. This paper put forward a calculational method to base the mathematic model
the calculational method was multi-population genetic algorithm (MPGA). After the 0-1 variables and real multidimensional ones had been coded separately
the algorithm established the populations independently
made the multidimensional variables as the centrosome and combined 0-1 ones to work out the maximal value of the function which was established to describe the control mode of the optical payload. Moreover
the emulational experiment had been done with the material arithmetic operators. The result indicates that the method using MPGA can hurdle the disadvantage of traditional ones which calculate slowly and get into local best value trap easily . It has the characters that not only fits large scale area scout
but also gets the best value in full scale rapidly
so this algorithm can better satisfy the technology demand for the intelligent control of optical payload. 2009 IEEE.

Munsell color system is selected to establish the mutual conversion between RGB and L*a*b* color model for camera. The color luminance meter and CCD camera synchronously measure the same color card
XYZ value is gotten from the color luminance meter
the training error is 0.000748566
it can show that the method combining second general revolving combination design with genetic algorithm can optimize the hidden-layer structure of neural network. Using the data of testing set to test this network and calculating the color difference between forecast value and true value
the color picture captured from CCD camera is expressed for RGB value as the input of neural network
and the L*a*b* value converted from XYZ value is regarded as the real color value of target card
which the difference is not obvious comparing with forecast result
the maximum is 5.6357 NBS
namely the output of neural network. The neural network of two hidden-layers is considered
the minimum is 0.5311 NBS
so the second general revolving combination design is introduced into optimizing the structure of neural network
and the average of color difference is 3.1744 NBS.
which can carry optimization through unifying project design
data processing and the precision of regression equation. Their mathematics model of encoding space is gained
and the significance inspection shows the confidence degree of regression equation is 99%. The mathematics model is optimized by genetic algorithm
optimization solution is gotten
and function value of the goal is 0.0007168. The neural network of the optimization solution is trained
