Today we are going to discuss approximation algorithms to two geometric problems:. The closest pair problem. The K-enclosing disc problem. Pair Programming. Every line of production code is written by two people working together at the same keyboard. No boss; at any time the co-pilot or navigator can take over for the pilot or driver. Should switch roles frequently, every 20-30 minutes as a rough guideline. Chuong. B. Do. CS262, Winter 2009. Lecture #8. Outline.
