The stochastic block model is one of the simplest models for a random graph with different types of vertices, known as communities. In this talk I will describe an efficient algorithm that distinguishes between vertices…
C# library that implements algorithms for the numerical solution of ordinary differential equations. The library incorporates .NET desktop and Silverlight builds.
The systematic normal form of lattices is a new echelon form of lattices in which the entries obey a certain co-primality condition. These lattices can be used to approximate efficiently any lattice, and hence are…
The first question we computer scientists ask when facing a new algorithmic challenge is: is it NP-hard, or is it in P? Surprisingly, for many important problems, the answer is “neither!” I will discuss recent…
