This paper deals with minimization of ESOPs (exclusive-or sum-of-products) which represent symmetric functions. Se propose an efficient simplification algorithm for symmetric functions, which guarantees the minimality for some subclass of symmetric functions, and present the minimum ESOPs for all 6-variable symmetric functions.
