Combinatorics

Introductory Combinatorics

• rating: 1

Looks interesting -- it's interesting how close combinatorics is to discrete math.

Analytic Combinatorics

• rating: 1

Has a lot which is beyond me, but there's some good stuff in here.

Introduction to Random Graphs

• rating: 0

Has a lot which is beyond me, but random graphs are obviously interesting and important, and it goes into a few applications and things.

Boltzmann Samplers for the Random Generation of Combinatorial Structures

• rating: 3

When you are writing some ad hoc code to generate a random structure -- for example, for a property test, or for NaNoGenMo -- there are two things you realize sooner or later:

• If the resulting structure doesn't have the properties you want, you can throw it out and start over.
• If the structure is recursive, you need to be careful about the probability of recursing; if it's too high, there is a tendency for your structures to grow indefinitely.

The theory of Boltzmann Samplers formalizes these two things.

Not technical -- a certain amount of philosophizing, popularizing, and reminiscing.
