In this paper we use evolutionary algorithms and neural nets to solve fuzzy equations. In Part I we: (1) first introduce
our three solution methods for solving the fuzzy linear equation A¯X¯ + B¯= C¯; for X¯ and (2) then survey the results for
the fuzzy quadratic equations, fuzzy differential equations, fuzzy difference equations, fuzzy partial differential equations,
systems of fuzzy linear equations, and fuzzy integral equations; and (3) apply an evolutionary algorithm to construct one
of the solution types for the fuzzy eigenvalue problem. In Part II we: (1) first discuss how to design and train a neural
net to solve A¯X¯ + B¯= C¯ for X¯ and (2) then survey the results for systems of fuzzy linear equations and the fuzzy quadratic.
