Shedding light on El Farol
Damien Challet, Matteo Marsili, Gabriele Ottino
We mathematize El Farol bar problem and transform it into a workable model. In general, the average convergence to optimality at the collective level is trivial and does not even r…
Closed source versus open source in a model of software bug dynamics
Damien Challet, Yann Le Du
We introduce a simple microscopic description of software bug dynamics where users, programmers and a maintainer interact through a given program, with a particular emphasis on bug…
Bug propagation and debugging in asymmetric software structures
Damien Challet, Andrea Lombardoni
Software dependence networks are shown to be scale-free and asymmetric. We then study how software components are affected by the failure of one of them, and the inverse problem of…
