Global Optimization with Polynomials
(2004-01)The class of POP (Polynomial Optimization Problems) covers a wide rang of optimization problems such as 0 - 1 integer linear and quadratic programs, nonconvex quadratic programs and bilinear matrix inequalities. In this ... -
A Constraint Handling Strategy for Bit-Array Representation GA in Structural Topology Optimization
(2004-01)In this study, an improved bit-array representation method for structural topology optimization using the Genetic Algorithm (GA) is proposed. The issue of representation degeneracy is fully addressed and the importance of ... -
Computing Upper and Lower Bounds for the J-Integral in Two-Dimensional Linear Elasticity
(2004-01)We present an a-posteriori method for computing rigorous upper and lower bounds of the J-integral in two dimensional linear elasticity. The J-integral, which is typically expressed as a contour integral, is recast as a ...
