Properties of Gray and binary representations (2008)
Jonathan Rowe, Darrell Whitley, Laura Barbulescu
Representations are formalized as encodings that map the search space to the vertex set of a graph. We define the notion of bit equivalent encodings and show that for such encodings the corresponding...

Geiringer’s theorem is a statement which tells us something about the limiting frequency of occurrence of a certain individual when a classical genetic algorithm is executed in the absence of...
Gray, Binary and Real Valued Encodings: Quad Search and Locality Proofs (2008)
Darrell Whitley, Jonathan Rowe
Abstract. This paper looks at proofs concerning Gray codes and the locality of local search; it is shown that in some cases such proofs can be generalized to Binary and real valued encodings, while...

Tight Bounds for Blind Search on the Integers (2008)
Dietzfelbinger, Martin, Rowe, Jonathan, Wegener, Ingo, Woelfel, Philipp
We analyze a simple random process in which a token is moved in the interval $A=\{0,\dots,n\$: Fix a probability distribution $\mu$ over $\{1,\dots,n\$. Initially, the token is placed in a random...

Natural selection in chemical evolution (2007)
Chrisantha Fernando, Jonathan Rowe
We propose that chemical evolution can take place by natural selection if a geophysical process is capable of heterotrophic formation of liposomes that grow at some base rate, divide by external...
Propagation Time in Stochastic Communication Networks (2006)
Rowe, Jonathan, Mitavskiy, Boris
Dynamical processes taking place on networks have received much attention in recent years, especially on various models of random graphs (including small world and scale free networks). They model a...
An extension of geiringer’s theorem for a wide class of evolutionary search algorithms (2006)
Boris Mitavskiy, Jonathan Rowe
The frequency with which various elements of the search space of a given evolutionary algorithm are sampled is affected by the family of recombination (reproduction) operators. The original Geiringer...
Bollier, David, Rowe, Jonathan
"The idea of the free market has become so widespread its hard to remember when public stadiums werent named for private corporations. But evidence is mounting--from catastrophic climate disruption...
The Majesty of the Commons: A Review of David Bollier's 'Silent Theft' (2002)
From article: "The train is coming. So it's a good time to pause and ask some basic questions, and that's what David Bollier has done in 'Silent Theft: The Private Plunder of Our Common Wealth.' The...
"Two centuries and some ago, people looked at the economic life around them and saw many different things. They saw factories and farms, shipping firms and theaters, and on and on. Then Adam Smith...
