Note to the participants in the Master -------------------------------------- **REV.** indicates revision with respect to the material given to you during the lectures. We suggest that, as a minimum, you download the material indicated with **REV.**, in particular, the following: - "lecture 3 part B" - the revised model "brooks_law_rev.zip", though its revision only incorporates changes in the names of some of the variables. Model structure and equations remain the same - the revised model "evolution1rev.zip", which incorporates corrections to some problems of its previous version, and in general, a clearer, we hope, structure. We changed some of the equations, including the "synergy" term, which now follows a different, but qualitatively equivalent, formulation. See also the charts for "lecture 3 part B" which now include an explanation of the revised model - the revised lab instructions "lab 2" We also suggest that you finalise the compulsory part of lab 2 related to "evolution1rev.zip" using the revised model. The models are provided as a "zip" file. Please "unzip" before doing anything else. By the way, we are available to try to answer any of your questions. Please e-mail us at with any questions, comments and/or suggestions. Many thanks for your attention and interest during the all too short lectures and labs. All best wishes, Juan F.
