Embedding the gradient direction search and new kinds of evaluation functions into the Genetic Algorithm, a special hybrid Genetic Algorithm with mutation along the weighted gradient direction to solve non-linear programming problems is developed. Then in Chapt 4, a type of nonlinear programming problems with fuzzy objective and fuzzy resources constraints is discussed, in which the objective is ill-defined and the resources possess two different types of fuzzy resources, i. e., tolerance and imprecision. By way of description and formulation of fuzzy objective and fuzzy resources, the problem with fuzzy objective and two different types of fuzzy resources is modelled into a fuzzy nonlinear programming model FO/RNLP and interpreted as three equivalent alternative crisp model to reflect the variety of the environment and the subjective and preference of the decision maker .

He correspondence between two point set surfaces was established based on the deformation gradient and the moving least square method. The deformation gradient was decomposed into a rotation and a stretching component with the matrix polar factorization. Then each component was interpolated in dividually over the time. Shape interpolation was implemented through a global quadric energy optimization.

G.E.Hubb root is from 0.20mm to 0.50mm, and 95% roots, diameter is thinner than 0.40mm. The total surface areas of roots is 10139.68cm^2, and the surface areas of roots is about 2 to 3 times to soil surface areas in the surface layer. Enlacing sod concretion to soil profile of Eulaliopsis binata G.E. Hubb root and the gigantic adsorption to soil grains of root surface are the mechanism why Eulaliopsis binata G.E.
