In this page you find proposals for research internships and PhDs when available as well as draft versions of papers which are in progress. Sometimes they have appeared as working papers and/or technical reports of LAMSADE or other Research Centers I have been invited. You are welcome to download and forward to me any comments you like. However, please do not quote them without permission (the Cahiers can be downloaded from the LAMSADE main page).


More or less published material.

Alberto Colorni, Alexis Tsoukiās: What is a decision problem? There are two papers here: one is published within the proceedings of ADT 2013 (see here a preliminary version); the other is still work in progress, but you can see a preliminary version here appeared in a edited volume this year (see also the page with published papers). With Alberto we are preparing a long paper on this subject.  Out of this material we also wrote a short paper which follows: A. Colorni, A. Tsoukiās, ``Sorting or Rating: terminology matters’’, in Journal of MCDA (see the published papers page).


Most of my recent work appears as Cahiers du LAMSADE and within ArXiv. The ArXiv page is the following one:
