Example cases

When trying to explain a complex abstraction, start with the simplest case, and build outward toward the most complex.

In Algorithms to Live By, the Threshold Approach to the Full Information Halting Problem is explained by starting with only a single applicant, which isn't really a choice at all. The example then moves to two applicants, where the applicant is only selected if they are in the top 50% of applicants, etc. This was an extremely succinct way of explaining the math of selection.
