On sparse approximations to randomized strategies and convex combinations

TLDR
An approximation lemma is presented and it is shown that in all cases arbitrary probability vectors can be replaced by sparse ones (with only logarithmically many positive entries) without losing too much performance.

Playing large games using simple strategies

TL;DR: The existence of ε-Nash equilibrium strategies with support logarithmic in the number of pure strategies is proved and it is proved that if the payoff matrices of a two person game have low rank then the game has an exact Nash equilibrium with small support.

Randomized rounding without solving the linear program

TL;DR: A new technique called oblivious rounding is introduced a variant of randomized rounding that avoids the bottleneck of first solving the linear program, which yields more efficient algorithms and brings probabilistic methods to bear on a new class of problems.

Progress in approximate nash equilibria

TL;DR: A polynomial algorithm is given for computing an ε-approximate Nash equilibrium in 2-player games with ε ≈ .38; the algorithm computes equilibria with arbitrarily large supports.

Randomized Rounding without Solving the Linear Program

TL;DR: In this article, the authors explore how to avoid the time bottleneck for randomized rounding algorithms for packing and covering linear programs (either mixed integer linear programs or linear programs with no negative coefficients).

A note on approximate nash equilibria

TL;DR: A simple, linear-time algorithm is given, examining just two strategies per player and resulting in a -approximate Nash equilibrium in any 2-player game, and it is shown that an approximation of is possible contingent upon a graph-theoretic conjecture.

On the Uniform Convergence of Relative Frequencies of Events to Their Probabilities

TL;DR: This chapter reproduces the English translation by B. Seckler of the paper by Vapnik and Chervonenkis in which they gave proofs for the innovative results they had obtained in a draft form in July 1966 and announced in 1968 in their note in Soviet Mathematics Doklady.
