search method or any given pre-design method.
Then, one damper of
I
0
is removed by its initial
position and it is placed at each of
(n-r)
unused
locations (not included in
I
0
) and the objective
function is evaluated. This process is repeated for
each of the
r
dampers of
I
0
so globally
r×(n-r)
combinations are considered and the correspond-
ing objective functions are evaluated (Table 3
and Figure 3). Then, the configuration with the
best objective function is denoted by
I
2
. It is
obvious from above discussion that the ESPS
search method is more general than WOBI one,
because it considers all possible configurations. In
ESPS search, a total of
r×(n-r)
evaluations of the
objective function are required in each iteration
to find the optimal location, while WOBI search
tries only
n
configurations.
