Abstract--- Multi­objective optimization problems, in gen­
eral, exhibit several local optima besides a global one. A
desirable feature of any optimization strategy would there­
fore be to supply the user with as many information as pos­
sible about local optima on the way to the global solution.
In this paper a hierarchical clustering algorithm is imple­
mented into a higher order Evolution Srategy is applied to
achieve these goals.
I. Introduction
Stochastic methods have been widely accepted for the
solution of real world optimization problems. A substan­
tial di#erence to deterministic methods is, that stochastic
