Highlights of this year's issue include articles on sequential quadratic programming, mesh adaption, free boundary problems, and particle methods in continuum computations. The invited papers will allow researchers and graduate students alike to quickly grasp the current trends and developments in this field.1. Sequential quadratic programming Paul T. Boggs; 2. A taste of Pad? approximation C. Brezinski and J. van Iseghem; 3. Introduction to adaptive methods for differential equations Kenneth Eriksson, Don Estep, Peter Hansbo and Claes Johnson; 4. Exact and approximate controllability for distributed parameter systems R. Glowinski and J. L. Lions; 5. Numerical solutions to free boundary problems Thomas Y. Hou; 6. Particle methods for the Boltzmann equation Helmut Neunzert and Jens Struckmeier; 7. The new QD algorithms Beresford N. Parlett.Review of the hardback: 'Acta Numerica is a fine achievement and I think we can expect to see it for many years to come. It sets itself laudable and important goals and has, to a large extent, achieve them. I believe that the volumes are of enormous benefit to our subject & The editorial board should be applauded for having the vision and drive necessary to create and sustain such a high quality publicatiol
