针对在DP问题算法的设计和推导中缺乏对DP问题函数式建模算法与验证的细致研究,该文首先通过深入分析最大半环与DP类问题递推关系式的对应关系,找到满足最大半环性质的一类DP问题,使用最大半环对该类DP问题进行函数式建模;然后将实现的基于最大半环的函数式建模算法与Wimmer定义的递归函数结果进行等价性验证,从而保证了函数式建模算法的正确性;最后通过对lcs问题案例分析,验证了该方法的可行性和有效性.
The Functional Modeling and Verification of Dynamic Programming Problems Based on Max_Semiring
Functional modeling algorithms and verification frameworks for DP issues are not thoroughly studied in the literature,which mostly concentrates on the design and derivation of algorithms for DP problems.Firstly,the re-lationship between the maximum half-loop and the recursive equation of DP issues is examined,a class of DP prob-lems that have the maximal half-loop property are identified,and then this class of DP problems using the maximal half-loop are functionally described.Secondly,in order to confirm that the functional modeling algorithm used in this study is valid,the output of Wimmer's recursive function with the maximum half-loop-based functional mode-ling technique are made equivalence checking.Finally,case examples of lcs difficulties illustrate the method's via-bility and efficacy.
