Variationally Constrained Numerical Solution of Electrical Impedance Tomography
We propose a novel, variational inversion methodology for the electrical impedance tomography problem, where we seek electrical conductivity σ inside a bounded, simply connected domain Ω, given simultaneous measurements ...
Computational Experience with Lenstra's Algorithm
Integer programming is an important mathematical approach for many decision-making problems. In this field, a major theoretical breakthrough came in 1983 when H. W. Lenstra, Jr. proposed a polynomial-time algorithm for a ...
A Successive Linear Programming Approach to IMRT Optimization Problem
We propose to solve the IMRT optimization problem through a successive linear programming approach. Taking advantage of the sensitivity information in linear programming and the re-optimization ability of simplex methods, ...
A Global Optimization Method for the Molecular Replacement Problem in X-ray Crystallography
The primary technique for determining the three-dimensional structure of a protein molecule is X-ray crystallography, from which the molecular replacement (MR) problem often arises as a critical step. The MR problem is a ...
