Normalization Algorithm of Coefficient Based on Denominator Digestion for Solving Complicated Permutation Issues with Exponential Generating Function
Solving R-reusable permutation of inexactly distinct elements with exponential generating functions is quite effectual. After obtaining the exponential generating function for that issue, the normalization of coefficients of every xr in the exponential generating function becomes the key question. Computational Complexity of general method is very high and it will be easy to generate bigger error because of computing the value of n!. Therefore this paper has put forward a kind of normalization algorithm of coefficient based on denominator digestion. It doesnt compute the value of n! and can quickly implement normalization of every xr in the exponential generating function. The algorithm is programmed by C++. The result of the program illustrates correctness and applicability of the algorithm.
