Abstract

A decomposition method, used in least-weight plastic design, is extended to solve problems with nonlinearity arising from variable structure geometry. The problem considered is that of finding vectorsx1,x2, andq that minimize [l max{|x1|, |x2|}], subject toAx1=b1 andAx2=b2, where both the vectorl and the matrixA are nonlinear functions ofq.
