Computer Science/Discrete Mathematics Seminar I

Using the DFS Algorithm for Finding Long Paths in Random and Pseudo-Random Graphs
11:15am|S-101

The Depth First Search (DFS) algorithm is one of the most standard graph exploration algorithms, used normally to find the connected components of an input graph. Though perhaps less popular than its sister algorithm, Breadth First Search (BFS), the...

Non-equilibrium Dynamics and Random Matrices

Universal current fluctuations in non equilibrium systems
Bernard Derrida
4:00pm|S-101

Fluctuations of the current of one dimensional non equilibrium diffusive systems are well understood. After a short review of the one dimensional results, the talk will try to show that the statistics of these fluctuations are exactly the same in...

Non-equilibrium Dynamics and Random Matrices, 2013-14

 

Over the past few decades there has been considerable progress in the mathematical analysis of equilbrium statistical mechanics. However, non-equilibrium dynamics is still at early stages of its...

Computer Science/Discrete Mathematics Seminar I

Association Schemes, Non-Commutative Polynomials and Lasserre Lower Bounds for Planted Clique
1:30pm|S-101

Finding cliques in random graphs and the closely related "planted" clique variant, where a clique of size k is planted in a random G(n,1/2) graph, have been the focus of substantial study in algorithm design. Despite much effort, the best known...

Nondeterministic Direct Product Reductions and the Success Probability of SAT Solvers
10:30am|S-101

In this talk I will describe nondeterministic reductions which yield new direct product theorems (DPTs) for Boolean circuits. In our theorems one assumes that a function F is "mildly hard" against *nondeterministic* circuits of some size s(n) , and...
