This page describes the workshop I will organize during the next ESSID Summer School.
Note: You can now download the lecture notes of the course (you must remember the link I have given during the workshop).
This workshop proposes an appraisal of different strategies that are available to us when we desire to include individual learning with bounded rationality in agent based evolutionary models. The R&D investment decisions of firms in the Nelson & Winter (1982, part V) model is used as a testbed for these strategies. You consult a quick description of the original model from this page. This is a required reading for the workshop. Other required documents are signalled below with a (*).
After some general
considerations about the modelling of bounded rationality, learning and
expectations, we will consider more in detail
some specific modelling technics that have are used to represent this learning: simple adaptation of behavioral rules, evolutionary mechanisms
(mutation and imitation), genetic algorithms and classifier systems, and artificial neural networks. The structure and relevance of these
technics will be discussed.
During the last hour of the workshop, experiments in the computer lab will
be conducted in order to compare the relative performance of these
approaches using my
Some of the references can be downloaded from my web page.
