Only five years after the initiation of transgenic research in plants, gene targeting (GT) was achieved for the first time in tobacco. Unfortunately, the frequency of targeted integration via homologous recombination (HR) was so low in comparison to random integration that GT could not be established as a feasible technique in higher plants.

Interior point methods for optimization have been around for more than 25 years now. Their presence has shaken up the field of optimization. Interior point methods for linear and (convex) quadratic programming display several features which make them particularly attractive for very large scale optimization. Among the most impressive of them are their lowdegree polynomial worst-case complexity ...
