It seems there is a relative scarcity of books on advanced problem solving. Most of the literature on this topic is either on more introductory problems or presents its material in much the same way that  Descartes criticises.  One would be inclined to think  that the latter are like foxes walking on snow but erasing their trails with their tails. Nikolaos defied the challenges and produced a book that  throws light  on the ideas and intricacies that lead to solutions for a variety of intriguing mathemati- cal problems. He draws his material mostly from challenging problems that have appeared in International Mathematical Competitions&#8230;\u201d<\/p>\n<p>Part of Prof. Michael Lambrou\u2019s foreword.<\/p>\n<p>\u201c\u2026, the purpose of the book is to present  a plethora of problems from all areas of contest mathematics and to present not only their solutions but the thinking trails one could follow to reach them. There is a huge difference between the two approaches and the author strongly feels that  the second proves to be a lot more didactic than the first one. Hopefully, as we said before, by the end of this book readers will be able to observe that a set of ideas to be presented tend to appear again and again; and that, if used on a regular basis, these will evidently hone their skills on problem solving.<\/p>\n<p>In parallel, this book aims to serve one more purpose: To act as a companion\/ mathematical coach to the reader, regardless  of his\/her  geographic location, ability to have one available on a regular basis, or any other factors whatsoever.<\/p>\n<p>It is also worth  mentioning that,  though the book is written  in the English language, the author primarily  wrote it in the hope that it aids to any extent towards improving the teaching of mathematics to gifted students in Greece, from early stages of competitions to members of the Greek National Teams.\u201d<\/p>\n<p>Part of author\u2019s introduction.<\/p>","protected":false},"excerpt":{"rendered":"<p>\u0388\u03bd\u03b1 \u03b2\u03b9\u03b2\u03bb\u03af\u03bf \u03b3\u03c1\u03b1\u03bc\u03bc\u03ad\u03bd\u03bf \u03c3\u03b5 \u03b1\u03c0\u03bb\u03ac \u03ba\u03b1\u03b9 \u03ba\u03b1\u03c4\u03b1\u03bd\u03bf\u03b7\u03c4\u03ac \u03b1\u03b3\u03b3\u03bb\u03b9\u03ba\u03ac, \u03bc\u03b5 \u03c0\u03b1\u03c1\u03b1\u03b4\u03b5\u03af\u03b3\u03bc\u03b1\u03c4\u03b1 \u03b1\u03c0\u03cc \u03cc\u03bb\u03bf\u03c5\u03c2 \u03c4\u03bf\u03c5\u03c2 \u03c7\u03ce\u03c1\u03bf\u03c5\u03c2 \u03c4\u03c9\u03bd \u039c\u03b1\u03b8\u03b7\u03bc\u03b1\u03c4\u03b9\u03ba\u03ce\u03bd \u039f\u03bb\u03c5\u03bc\u03c0\u03b9\u03ac\u03b4\u03c9\u03bd, \u03bc\u03b5 \u03c0\u03b1\u03c1\u03bf\u03c5\u03c3\u03af\u03b1\u03c3\u03b7 \u03c4\u03c9\u03bd \u03b1\u03bd\u03c4\u03af\u03c3\u03c4\u03bf\u03b9\u03c7\u03c9\u03bd \u03bb\u03cd\u03c3\u03b5\u03c9\u03bd \u03b1\u03bb\u03bb\u03ac \u03ba\u03b1\u03b9 \u03c4\u03bf\u03c5 \u03c3\u03ba\u03b5\u03c0\u03c4\u03b9\u03ba\u03bf\u03cd \u03c0\u03bf\u03c5 \u03bf\u03b4\u03b7\u03b3\u03b5\u03af \u03c3\u03b5 \u03b1\u03c5\u03c4\u03ad\u03c2. \u201c\u2026It is a unique book.
