R. D'Hulst, G. J. Rodgers
We show that a cut-and-paste model to mimic a trial-and-error process of adaptation displays two pairs of percolation and depinning transitions, one for persistence and the other f…

Efficiency and persistence in models of adaptation
R. D'Hulst, G. J. Rodgers
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 chara…

Exact Solution of a Model for Crowding and Information Transmission in Financial Markets
R. D'hulst, G. J. Rodgers
An exact solution is presented to a model that mimics the crowding effect in financial markets which arises when groups of agents share information. We show that the size distribut…
