"Combinatorial Programming" are two words whose juxtaposition still
strike us as unusual, nevertheless their association in recent years
adequately reflects the preoccupations underlying differing work fields,
and their importance will increase both from methodology and application
view points. To those who like definitions and consider the function of
this book to furnish one for combinatorial programming, I will simply
say that it is precise- ly this which is exclusively treated here and
which in the eyes of the autors is the heart of this branch of applied
mathematics. Such was the initial intention of those who in the spring
of 1973 gathered tog ther in Paris to state the work of the Advanced
Study Institute from which this book arises. As young as combinatorial
programming is, it was easy to see that a two week school was
insufficient to cover the subject in an exhaustive manner. Finally the
decision had to be taken to reduce to book form, and to organise within
this particular means of expression, the essential syntheses and
communications. Unfortunately the discussions, the round tables, and the
majority of the case studies could not be included in this book which is
more of a hand-book on the subject. XIV PREFACE The choice and
orientation of the surveys has been guided by two criteria: the
importance of already accomplished work, and the originality of the
survey to be undertaken.
