Examples
- The main work of the paper is summarized as followings : the algorithm is improved somewhat , the algorithm is implemented in pc by mathematica software and the effectivity is proved to by testing all the examples that have been proved by d . zeilberg and h . wilf using wz - pair method and testing many identities of the book named " combinatorial identities " , which was written by h . w . gould in 1972
本文的主要结果为：对算法作了一定的改进；在微机上，用数学软件mathematica实现了这种算法；试算了d . zeilberg和h . wilf用wz对方法算过的所有例题，对h . w . gould的一本名为“ combinatorialidentities ”的书中大量恒等式也作了验证。 - In view of the great sense of making profit to a commercial bank , this dissertation applys maths modeling theory and layer analysis , takes modern computer technology , uses advanced maths software and finally constructs a profit maxmization model for commercial bank according to the real situations of commercial bank operation ; it also takes the operation of a certain home bank for example , applys the constructed profit model to its operation so as to make assets allocated best and realizes its assets profit maxmiazation
