Problem Solving Strategies Arthur Engel Pdf Site

But what makes this 400+ page behemoth so special? Is it worth printing out, or is it just another problem collection? Let's dive in.

Unlike modern "tricks" books, Engel forces you to think like a detective. For example, his chapter on The Invariance Principle teaches you to look for what doesn't change in a system. A dragon has 100 heads. A knight can cut off 15, 21, or 17 heads, but if he cuts off 15, 21 new heads grow; if he cuts off 21, 14 grow; if he cuts off 17, 0 grow. Can the knight ever kill the dragon? Most students will try brute force. Engel teaches you to check the invariant (modulo 3). The PDF format allows you to stare at that problem, fail, and then scroll down one inch to see the elegant modular arithmetic solution. That "Aha!" moment is the entire point. problem solving strategies arthur engel pdf
