Fuzzy Submodularity Function And Fuzzy Rank Function
WU De-yin · Mohu xitong yu shuxue · 2007
First,we study some properties of fuzzy sets.Then,we define fuzzy submodularity functions according to the pattern of submodularity function,and investigate some properties of fuzzy submodularity function and fuzzy rank function.Finally,we utilize these properties to extend an important theorem of getting fuzzy matroids by the fuzzy rank functions.
