The major challenge when working with permutations is that the factorial function gets very, very large very, very quickly. The BigInteger data type was introduced in the .NET Framework 4.0; it ...

Abstract: Kløve et al. proposed permutation codes under Chebyshev distance and iterative encoding and decoding algorithms for the permutation code. In this paper, we introduce a factor graph of the ...

Abstract: We address an important issue in the design of concentric permutation code based vector quantizers to select the optimal integer partitions. We establish that, for concentric permutation ...

In order to use the C++ code, you'll have to install igraph for C. To do so, follow the instructions at the website: http://igraph.org/c/ As seen in the Makefile, the ...
