The Burrows-Wheeler Algorithm

The Burrows-Wheeler Algorithm was published in the year 1994 by Michael Burrows and David Wheeler in the research report “A Block-sorting Lossless Data Compression Algorithm”. This research report is based on an unpublished work by David Wheeler from the year 1983. The Burrows-Wheeler Algorithm will used for data compression. The algorithm consists of several stages and these stages are perform...

Wheeler Graphs: Variations on a Theme by Burrows and Wheeler

The famous Burrows-Wheeler Transform was originally defined for single strings but variations have been developed for sets of strings, labelled trees, de Bruijn graphs, alignments, etc. In this talk we propose a unifying view that includes many of these variations and that we hope will simplify the search for more. Somewhat surprisingly we get our unifying view by considering the Nondeterminist...

Against the Wheeler-DeWitt equation

The ADM approach to canonical general relativity combined with Dirac’s method of quantizing constrained systems leads to the Wheeler-DeWitt equation. A number of mathematical as well as physical difficulties that arise in connection with this equation may be circumvented if one employs a covariant Hamiltonian method in conjunction with a recently developed, mathematically rigorous technique to ...

This chapter reviews what has been learned about animal thinking from the study of animal communication, and considers what we might hope to learn in the future. It begins with a discussion on the importance of informational versus non-informational interpretations of animal communication and then considers what inferences can be drawn about the cognitive requirements of communication from the ...
