ON NUMERICAL RESULTS FOR SHAPE OPTIMIZATION
IFAC Proceedings Volumes, 1989In this paper we are concerned with numerical solutions for shape optimization problems associated with elliptic partial differential equations. Our main motivation is a thermal problem where one wants to find an optimal boundary such that the heat loss is minimized for a fixed volume of insulation material.

Wing design by numerical optimization
Aircraft Systems and Technology Meeting, 1977A study was conducted to assess the feasibility of performing computerized wing design by numerical optimization. The design program combined a full potential, inviscid aerodynamics code with a conjugate gradient optimization algorithm. Three design problems were selected to demonstrate the design technique.

Superoscillations with Optimal Numerical Stability
IEEE Signal Processing Letters, 2014A bandlimited signal can oscillate at a rate faster than its bandlimit. This phenomenon, called "superoscillation", has ap- plications e.g. in superresolution and superdirectivity. The syn- thesis of superoscillations is a numerically difficult problem.

A Hybrid Particle Swarm Optimization for Numerical Optimization
2009 International Conference on Business Intelligence and Financial Engineering, 2009Particle Swarm Optimization (PSO) has shown its good performance on numerical function problems. However, on some multimodal functions the PSO easily suffers from premature convergence because of the rapid decline in velocity. This paper presents a hybrid PSO for numerical optimization, namely HPSO, which employs opposition-based learning (OBL) and a ...

Numerical optimization in hybrid symbolic-numeric computation
Proceedings of the 2007 international workshop on Symbolic-numeric computation, 2007Approximate symbolic computation problems can be formulated as constrained or unconstrained optimization problems, for example: GCD [3,8,12,13,23], factorization [5,10], and polynomial system solving [2,25,29]. We exploit the special structure of these optimization problems, and show how to design efficient and stable hybrid symbolic-numeric algorithms

On the role of optimality functions in numerical optimal control
Annual Reviews in Control, 2011Abstract We present a survey of optimality conditions in optimality function form and discuss their role in establishing that discretized optimal control problems are consistent approximations to the original optimal control problems.
