On the Problem of Optimal Material Distribution
, 1996 The paper considers the problem of optimum distribution of two materials with a linear scalar elliptic PDE as the state problem and a general objective functional, not only compliance.

Maximizing Band Gaps In Two-Dimensional Photonic Crystals
. Photonic crystals are periodic structures composed of dielectric materials, and designed to exhibit band gaps i.e., ranges of frequencies in which electromagnetic waves cannot propagate, or other interesting spectral behavior.

, 1997 . The Nelder-Mead algorithm can stagnate and converge to a non-optimal point, even for very simple problems. In this note we propose a test for sufficient decrease which, if passed for the entire iteration, will guarantee convergence of the Nelder-Mead ...

Optimal Generalized Cubature Technique for Constructing Higher-Precision Cubature Rules
This paper presents a generalized cubature technique for constructing higher-precision cubature rules from existing lower-precision rules. By combining the Anti-Gaussian 3-point, Fejer’s second 3-point, and Lobatto 4-point cubature rules through an ...

A Discontinuous Finite Element Method For Solving A Multi-Well Problem
, 1998 . Many physical materials of practical relevance can attain several variants of crystalline microstructure. The appropriate energy functional is necessarily non-convex, and the minimization of the functional becomes a challenging problem. A new numerical
