This volume contains refereed papers based on the lectures presented at
the XIV International Conference on Mathematical Programming held at
Matrahaza, Hungary, between 27-31 March 1999. This conference was
organized by the Laboratory of Operations Research and Deci- sion
Systems at the Computer and Automation Institute, Hungarian Academy of
Sciences. The editors hope this volume will contribute to the theory and
applications of mathematical programming. As a tradition of these
events, the main purpose of the confer- ence was to review and discuss
recent advances and promising research trends concerning theory,
algorithms and applications in different fields of Optimization Theory
and related areas such as Convex Analysis, Complementarity Systems and
Variational Inequalities. The conference is traditionally held in the
Matra Mountains, and housed by the resort house of the Hungarian Academy
of Sciences. This was the 14th event of the long lasting series of
conferences started in 1973. The organizers wish to express their thanks
to the authors for their contributions in this volume, and the anonymous
referees for their valu- able comments. Special thanks are directed to
our sponsors, the Hun- garian Academy of Sciences, the National
Committee for Technological Development, the Hungarian National Science
Foundation, and last but not least, the Hungarian Operational Research
Society. We would like to thank John Martindale from Kluwer Academic
Publishers for helping us produce this volume, Eva Nora Nagy for cor-
rections and proof-readings, and Peter Dombi for his excellent work on
typesetting and editing the manuscript.
