Abstract
This thesis studies a class of optimization problems on sparse random (hyper-)graphs. Of central focus is the optimum value of these problems on graphs with a large number of vertices. The first part introduces a general framework to study the typical value of some combinatorial optimization problems on sparse random graphs, via a connection with mean-field spin glasses. An an application, we derive novel bounds on various combinatorial quantities such as Max-Cut, min-bisection, max XORSAT etc. The second part of this thesis studies a semi-definite relaxation of the min-bisection problem on sparse random graphs. As a consequence, we provide near optimal recovery guarantees for a natural semi-definite programming based algorithm for the community detection problem.
