When relevance judgment is absent, a voting algorithm is designed to replace the NIST relevance assessors. It generates the pseudo-relevance judgment needed by the trec_eval program, the standard TREC evaluation tool. The objective function in evolution process is tuned according to various considerations.

Northern blot analysis showed that the GFP gene was correctly expressed in the transgenic plants. Green fluorescence was observed in roots and immature embryos of transgenic plants by fluorescence microscopy.Progeny analysis showed that GFP insertions were inherited in T_2 generation with normal expression.Both Mendelian and non-Mendelian inheritances were observed in T_1 progenies of transgnic maize,and non-Mendelian inheritances were observed in T_2 progenies.

Southern blot结果表明GFP基因以低拷贝数、简单的方式(1～3条Southern杂交带)整合到玉米基因组；Northern blot结果表明GFP基因在转录水平上表达；在转基因植株的根和幼胚中观察到GFP表达；转基因植株的后代遗传分析表明GFP基因能够遗传至T_2代并正常表达，部分转基因株系中的GFP基因以孟德尔遗传方式传递给T_1代，但T_2代不符合孟德尔分离比。

In chapter 2, we proposed a fractal image coding method based on genetic algorithms. The searching scheme problem of domain block in fractal image coding is well solved by applying a robust genetic algorithm with well-selected populations and revised genetic operators. Experimental result has show that it can increase fractal image coding speed by this method.
