Query: Non-dominated Solution of Fuzzy Maximum-Return Problem   In this paper, we find a non-dominated solution of a fuzzy maximum-return
problem ( unconstrained single-variable fuzzy optimization problem ) . We
establish Newton method to find the solution of the unconstrained
single-variable fuzzy optimization problem using the differentiability of
$\alpha$-level functions of a fuzzy-valued function and partial order relation
on a set of fuzzy numbers.
