Some are worth killing for . . .

MANY YEARS HAVE PASSED SINCE WE WELCOMED THE FIRST STRANGERS INTO OUR HOME. I now feel qualified to comment on our experience and include information that we would have found helpful when we took what seemed at the time quite a brave step. My husband spent all his working life in the hospitality industry and we first met whilst studying hotel and catering management at the same college back in the late 50s. Now, nominally retired, we have gone full circle - back to serving meals and making beds - and enjoying it more than ever! The difference between then and now is that we fill our empty bedrooms with guests as a pleasure, rather than solely through financial necessity. Tolerance, flexibility and a sense of humour have been needed on occasions, but our guests have been absolutely great and since starting our business our faith in humanity has soaredA".

The new 6th edition of Applied Combinatorics builds on the previous editions with more in depth analysis of computer systems in order to help develop proficiency in basic discrete math problem solving. As one of the most widely used books in combinatorial problems, this edition explains how to reason and model combinatorically while stressing the systematic analysis of different possibilities, exploration of the logical structure of a problem, and ingenuity. Although important uses of combinatorics in computer science, operations research, and finite probability are mentioned, these applications are often used solely for motivation. Numerical examples involving the same concepts use more interesting settings such as poker probabilities or logical games.
