Practical Applications of IndetermSoft Set and IndetermHyperSoft Set and Introduction to TreeSoft Set as an extension of the MultiSoft Set

Abstract

The IndetermSoft Set is as an extension of the Soft Set, because the data, or the function,
or the sets involved in the definition of the soft set have indeterminacy - as in our everyday life, and
we still need to deal with such situations.
And similarly, IndetermHyperSoft Set as extension of the HyperSoft Set, when there is
indeterminate data, or indeterminate functions, or indeterminate sets.
Herein, ‘Indeterm’ stands for ‘Indeterminate’ (uncertain, conflicting, incomplete, not unique
outcome).
We now introduce for the first time the TreeSoft Set as extension of the MultiSoft Set.
Several applications are presented for each type of soft set
