The algorithm has some problems, such as bias problem, aliasing problem and one problem that affects none-shade part of image and is caused by Gaussian blur. To solve these problems, this paper makes some improvement on the algorithm. Firstly, it uses the Woos average depth principle and PCF algorithm to solving bias problem and aliasing problem; secondly, it designs and implements an effective method to control the range of blur; thirdly, it adapts any size texture to story information. This method for keeping information plays important part on raising realistic graphic; fourthly, it takes use of the technology of programmable graphics hardware and the method of FBO to improve efficiency of algorithm.

Thirdly, we examine a job scheduling problem, in which jobs could be processed by multiple in-line steppers. This problem includes two decisions: job assignment and job sequencing. Through developing a new and concise representation scheme for modeling the two decisions, we solve the multiple-machine scheduling problem by various meta-heuristic algorithms. The preceding single-machine scheduling problem in fact is a special case of the multiple-machine scheduling problem.

Applying the De Caen"s inequality of sum of the squares of the degree and Cauchy"s inequality, we obtain a strict lower bound and a strict upper bound of the largest Laplace eigenvalues only in terms of vertex number of a unicycle graph. Applying the Laplace matrix theorem of trees, we obtain an upper bound of the second smallest Laplace eigenvalues of a unicycle. Extremal graph whose second smallest Laplace eigenvalues reach the obtained upper bound is determined. We also obtain an upper bound of the second largest Laplace eigenvalues in terms of vertex number of the largest connected branch of unicycle graph, and obtain a theoretical method to calculate the second largest Laplace eigenvalues of unicycle graph. We obtain an upper bound of any Laplace eigenvalues in terms of vertex number of a unicycle graph. We also obtain the distribution of Laplace eigenvalues in the inter [0,n] in terms of the matching number.
