	%X A non-stationary stochastic optimization methodology
is applied to an OWC (oscillating water column) to find the design
that maximizes the wave energy extraction. Different temporal cycles
are considered to represent the long-term variability of the wave
climate at the site in the optimization problem. The results of the
non-stationary stochastic optimization problem are compared against
those obtained by a stationary stochastic optimization problem. The
comparative analysis reveals that the proposed non-stationary
optimization provides designs with a better fit to reality. However,
the stationarity assumption can be adequate when looking at averaged
system response.
