Introduction

Learning Objectives:

  • Apply alteration method
  • Understand Lovász Local Lemma
  • Solve satisfiability problems

Lovász Local Lemma

If events A1,...,AnA_1, ..., A_n have limited dependencies and each P(Ai)leqpP(A_i) leq p, and dependency degree leqdleq d with ep(d+1)leq1ep(d+1) leq 1, then:

P(igcap_i overline{A_i}) > 0

Application: SAT problems with sparse dependencies

Applications

Apply these concepts to solve real-world problems in probability and statistics.

python
import numpy as np
