Generating Functions Lecturer : Michel Goemans

چکیده
We are going to discuss enumeration problems, and how to solve them using a powerful tool: generating functions. What is an enumeration problem? That’s trying to determine the number of objects of size n satisfying a certain definition. For instance, what is the number of permutations of {1, 2, . . . , n}? (answer: n!), or what is the number of binary sequences of length n? (answer: 2n). Ok, now let us introduce some tools to answer more difficult enumerative questions.

Probability Theory Lecturer : Michel Goemans
To treat probability rigorously, we define a sample space S whose elements are the possible outcomes of some process or experiment. For example, the sample space might be the outcomes of the roll of a die, or flips of a coin. To each element x of the sample space, we assign a probability, which will be a non-negative number between 0 and 1, which we will denote by p(x). We require that p(x) = ...
متن کاملMassachusetts Institute of Technology Lecturer : Michel X . Goemans 18 . 409 : Topics in TCS : Embeddings of Finite Metric Spaces
Recall that a series-parallel graph consists of an edge, or of two series-parallel graphs connected in series or in parallel. A graph can be decomposed into series-parallel blocks if and only if it has treewidth 2. It is easy to see that these graphs cannot, in general, be embedded isometrically into `1: consider, for example, the n-cycle. In this lecture, we shall show two different constant-d...
متن کاملLinear programming Lecturer : Michel Goemans 1 Basics
Linear Programming deals with the problem of optimizing a linear objective function subject to linear equality and inequality constraints on the decision variables. Linear programming has many practical applications (in transportation, production planning, ...). It is also the building block for combinatorial optimization. One aspect of linear programming which is often forgotten is the fact th...
متن کاملMassachusetts Institute of Technology Lecturer : Michel X . Goemans
The aim of this lecture is to outline the gluing of embeddings at different scales described in James Lee’s paper Distance scales, embeddings, and metrics of negative type from SODA 2005 [1]. We begin by recalling some definitions. A map f : X → Y of metric spaces (X, dX ) and (Y, dY ) is said to be C-Lipschitz if dY (f(x), f(y)) ≤ CdX(x, y) for all x, y ∈ X. The infimum of all C such that f is...
متن کاملFast Fourier Transform Lecturer :
In this section we discuss the theory of Fourier Series for functions of a real variable. In the next sections we will study an analogue which is the “discrete” Fourier Transform. Early in the Nineteenth century, Fourier studied sound and oscillatory motion and conceived of the idea of representing periodic functions by their coefficients in an expansion as a sum of sines and cosines rather tha...
