Efficiency and persistence in models of adaptation
A cut-and-paste model which mimics a trial-and-error process of adaptation is
introduced and solved. The model, which can be thought of as a diffusion
process with memory, is characterized by two properties, efficiency and
persistence. We establish a link between these properties and determine two
transitions for each property, a percolation transition and a depinning
transition. If the adaptation process is iterated, the antipersistent state
becomes an attractor of the dynamics. Extensions to higher dimensions are
briefly discussed.Comment: 4 pages, 4 figures, submitted to publicatio
