Gradient-only approaches to avoid spurious local minima in unconstrained optimization

Author: Wilke, DN ; Kok, S ; Snyman, JA ; Groenwold, AA Date: Jun 2013 We reflect on some theoretical aspects of gradient-only optimization for the unconstrained optimization of objective functions containing non-physical step or jump discontinuities. This kind of discontinuity arises when the optimization problem ... Read more
Solution of heat equation with variable coefficient using derive

Author: Lebelo, RS ; Fedotov, I ; Shatalov, M Date: Sep 2008 In this paper, the method of approximating solutions of partial differential equations with variable coefficients is studied. This is done by considering heat flow through a one-dimensional model with variable cross-sections. Two cases are ... Read more
