Intro to Algorithms & Euclid's Method for Students

In this lecture, the first of the 'Constructive Mathematics' first year undergraduate course, Patrick introduces algorithms, and the kinds of mathematical questions we study about them. He begins our study of algorithms with Euclid's method for computing greatest common divisors, an algorithm that has been used for 2300 years.
