1 Introduction
There are many optimizing procedures using sensitivity analysis or genetic algorithms,
and they are successfidly applied to a wide varaiety of practical problems.
In general, however, an optimizing procedure using sensitivity analysis frequently
fails to find the global minimum of an objective function, depending on the initial
values of parameters. The present paper is concerned with application of cellular
automata [I] [2] [3] [4] [5] combined with the boundv element method to
finding optimal shapes of the sound-insulating wall. In application of the cellular
automata, the domain of interest is discretized into a number of uniform cells.
Some quantity defining the cell state is assigned each cell, and then modi
