CSG: A new stochastic gradient method for the efficient solution of structural optimization problems with infinitely many state problems
2020
Structural And Multidisciplinary Optimization
This paper presents a novel method for the solution of a particular class of structural optimzation problems: the continuous stochastic gradient method (CSG). In the simplest case, we assume that the objective function is given as an integral of a desired property over a continuous parameter set. The application of a quadrature rule for the approximation of the integral can give rise to artificial and undesired local minima. However, the CSG method does not rely on an approximation of the
