Since Shallit's statement, Dembski has (as of May 2010) published four peer-reviewed papers in information theory venues associated with the IEEE professional society. The papers deal with "active information" in the context of searches for solutions to problems. Quantified active information is introduced in "Conservation of Information in Search: Measuring the Cost of Success." A second paper, "Evolutionary Synthesis of Nand Logic: Dissecting a Digital Organism," claims to deconstruct the evolution simulation Avida by uncovering the sources of active information in the program. A third paper discusses the role of Jacob Bernoulli's "principle of indifference" in the analysis of evolution. The most recent paper, "Efficient Per Query Information Extraction from a Hamming Oracle," calculates the performance of various search algorithms which use the Hamming distance to search for a single string of a certain length in the set of all strings of this length.
