The aim of this paper is to present a conceptual framework for the selective memetic evolution of strategies belonging to large organizations. The framework was designed as a basis for further research on policy formation processes. This research hopes to enhance our understanding of such processes, ultimately in order to design more efficient policy processes. This framework draws on analogies...

This document outlines possible TCP enhancements that may allow TCP to better utilize the available bandwidth provided by satellite networks. The algorithms and mechanisms outlined have not been judged to be safe for the global Internet. However, the mechanisms may be appropriate for private satellite networks (or other long-delay network paths). The goal of this document is to educate research...

Peter Dawkins is one of many expressing surprise that unemployment remains the wrong side of 6⁄2 per cent ‘after eight years of sustained strong growth’. An Okun-accounting approach might help. Albeit very crudely applied here, the Okun concentration is on GDP, labour productivity and labour force growth rates rather than elapsed recovery time alone. When the 1990s expansion is viewed through O...

The Collatz 3n+ 1 Conjecture states that for each n ∈ N, there exists an m ∈ N such that T (n) = 1, where T (n) is the function T iteratively applied m times to n. As of September 4, 2003, the conjecture has been verified for all positive integers up to 224× 2 ≈ 2.52× 10 (Roosendaal, 2003+). Furthermore, one can give a heuristic probabilistic argument (Crandall, 1978) that since every iterate o...

It is difficult to learn to program. We investigated if it is possible to predict programming aptitude of our students with Dehnadi-Bornat test early in order to give more attention to the students which are identified as less apt for programming. We present the results of the test and the correlation of test results and the final marks of courses of programming in the paper. We found out that ...

In this paper, we study the complexity of solving hard knapsack problems, i.e., knapsacks with a density close to 1 where latticebased low density attacks are not an option. For such knapsacks, the current state-of-the-art is a 31-year old algorithm by Schroeppel and Shamir which is based on birthday paradox techniques and yields a running time of Õ(2) for knapsacks of n elements and uses Õ(2) ...

Syndrome coding has been proposed by Crandall in 1998 as a method to stealthily embed a message in a cover-medium through the use of bounded decoding. In 2005, Fridrich et al. introduced wet paper codes to improve the undetectability of the embedding by enabling the sender to lock some components of the cover-data, according to the nature of the cover-medium and the message. Unfortunately, almo...

The history and theoretical role of the concept of a “replicator” is discussed, starting with Dawkins’ and Hull’s classic treatments and working forward. I argue that the replicator concept is still a useful one for evolutionary theory, but it should be revised in some ways. The most important revision is the recognition that not all processes of evolution by natural selection require that some...

Abstract Definitions of animal welfare often invoke consciousness or sentience. Marian Stamp Dawkins has argued that to define this way is a mistake. In Dawkins’s alternative view, an with good one healthy and “has what it wants.” The dispute highlights source strain on the concept welfare: consciousness-involving definitions are better able capture normative significance welfare, whereas consc...
