Ensemble Enumerators for Protograph-Based Generalized LDPC Codes
— Protograph-based LDPC codes have the advantages of a simple design (or search) procedure and highly structured encoders and decoders. These advantages have also been exploited ...

0/1 Vertex and Facet Enumeration with BDDs
In polyhedral studies of 0/1 polytopes two prominent problems exist. One is the vertex enumeration problem: Given a system of inequalities, enumerate its feasible 0/1 points. Anot...

The settling-time reducibility ordering
Abstract. To each computable enumerable (c.e.) set A with a particular enumeration {As}s∈ω, there is associated a settling function mA(x), where mA(x) is the last stage when a n...

Efficient Enumeration of Phylogenetically Informative Substrings
We study the problem of enumerating substrings that are common amongst genomes that share evolutionary descent. For example, one might want to enumerate all identical (therefore co...

Counting Polyominoes: A Parallel Implementation for Cluster Computing
The exact enumeration of most interesting combinatorial problems has exponential computational complexity. The finite-lattice method reduces this complexity for most two-dimension...
