Space vehicles have become increasingly complex in recent years, and the number of missions has multiplied as a result of extending frontiers in the exploration of our planetary system and the universe beyond. The advancement of automatic control in aerospace reflects these developments. Key areas covered in these proceedings include: the size and complexity of spacecrafts and the increasingly stringent performance requirements to be fulfilled in a harsh and unpredictable environment; the merger of space vehicles and airplanes into space planes to launch and retrieve payloads by reusable winged vehicles; and the demand to increase space automation and autonomy to reduce human involvement as much as possible in manned, man-tended and unmanned missions. This volume covers not only the newly evolving key technologies but also the classical issues of guidance, navigation and control.

This volume is based on papers presented at the 2nd International Conference on Computing Methods in Optimization Problems held in San Remo, Italy, September 9-13, 1968. The Conference was sponsored by the Society of Industrial and Applied Mathematicians (SIAM), with the cooperation of the University of California and the Univer- sity of California and the University of Southern Califor- nia. The Conference focussed on recent advances in com- putational methods for optimization problems in diverse areas including: Computational Aspects of Optimal Control and Trajec- tory Problems; Computational Techniques in Mathematical Programming; Computational Techniques in Optimization Problems in Economics, Metero1ogy, Biomedicine and Related Areas; Identification and Inverse Problems; Computational Aspects of Decoding and Information Retrieval Problems; Pattern Recognition Problems. The Organizing Committee of the Conference consisted of: A. V. Balakrishnan (U. S. A. ) - Chairman L. W. Neustadt (U. S. A. ) - Co-Chairman L. A. Zadeh (U. S. A. ) - Co-Chairman G. Debreu (U. S.
