What Is Combinatorics Anyway? Broadly speaking, combinatorics is the branch of mathematics dealing with different ways of selecting objects from a set or arranging objects. It tries to answer two major kinds of questions, namely, counting questions: how many ways can a selection or arrangement be chosen with a particular set of properties; and structural questions: does there exist a selection or arrangement of objects with a particular set of properties? The authors have presented a text for students at all levels of preparation. For some, this will be the first course where the students see several real proofs. Others will have a good background in linear algebra, will have completed the calculus stream, and will have started abstract algebra. The text starts by briefly discussing several examples of typical combinatorial problems to give the reader a better idea of what the subject covers. The next chapters explore enumerative ideas and also probability. It then moves on to enumerative functions and the relations between them, and generating functions and recurrences., Important families of functions, or numbers and then theorems are presented. Brief introductions to computer algebra and group theory come next. Structures of particular interest in combinatorics: posets, graphs, codes, Latin squares, and experimental designs follow. The authors conclude with further discussion of the interaction between linear algebra and combinatorics. Features Two new chapters on probability and posets. Numerous new illustrations, exercises, and problems. More examples on current technology use A thorough focus on accuracy Three appendices: sets, induction and proof techniques, vectors and matrices, and biographies with historical notes, Flexible use of MapleTM and MathematicaTM

Originally published in 1968, the study described in this title began in a very small way in late 1960. At that time some Oxfordshire county councillors and children’s department officials were very conscious that the number of children in care in the county was high in comparison with the national average. This meant that expenditure was also high. The County’s position, however, was not unique. Oxford City was in a similar position, but other neighbours did not appear to have the same problem. A small research project was launched to investigate and it soon became apparent that there was a large and complex problem to be solved. The problem was of striking, persistent and puzzling variations in the proportion of children in care in the different local authority children’s departments of England and Wales. This seemed to warrant a larger investigation on a country-wide basis and this book outlines the findings of that project.
