Typically-correct derandomization
A fundamental question in complexity theory is whether every randomized polynomial time algorithm can be simulated by a deterministic polynomial time algorithm (that is, whether B...

Thin Partitions: Isoperimetric Inequalities and a Sampling Algorithm for Star Shaped Bodies
Star-shaped bodies are an important nonconvex generalization of convex bodies (e.g., linear programming with violations). Here we present an efficient algorithm for sampling a giv...

Simple capacity-achieving ensembles of rateless erasure-correcting codes
—This paper is concerned with a simple binary erasure-recovery coding scheme that falls into the family of socalled semi-random low-density-parity-check (SR-LDPC) codes. Based on...

Iterative compression and exact algorithms
Iterative Compression has recently led to a number of breakthroughs in parameterized complexity. Here, we show that the technique can also be useful in the design of exact exponen...

Modelling Self-assembly in BlenX
Abstract. The process through which disordered components spontaneously arrange themselves into patterns is called self-assembly. Molecular self-assembly describes the process by w...
