Towards Sharp Inapproximability For Any 2-CSP
We continue the recent line of work on the connection between semidefinite programming-based approximation algorithms and the Unique Games Conjecture. Given any boolean 2-CSP (or...

A Ramsey Treatment of Symmetry
Given a space endowed with symmetry, we define ms(, r) to be the maximum of m such that for any r-coloring of there exists a monochromatic symmetric set of size at least m. We c...

Multi-way Partitioning for Minimum Delay for Look-Up Table Based FPGAs
In this paper we present a set cover based approach (SCP) to multi-way partitioning for minimum delay for Look-Up Table based FPGAs. SCP minimizes the number of chip-crossings on ...
