"Andreescu\'s 51 \'introductory problems\' and 51 \'advanced problems, \' all novel, would nicely supplement any university course in combinatorics or discrete mathematics.
The book gradually builds Combinatorial skills and techniques and not only broadens the student\'s view of mathematics, but is also excellent for Training teachers..
The text provides in-depth enrichment in the important areas of combinatorics by systematically reorganizing and enhancing problem-solving tactics and strategies. "--CHOICE 102 Combinatorial Problems consists of carefully selected problems that have been used in the Training and testing of the USA International Mathematical Olympiad (IMO) team. . .
This volume contains detailed solutions, sometimes multiple solutions, for all the problems, and some solutions offer additional twists for further thought .
