What do our previous students say about us? rammal   Hadia, class of 2010 I come from Lebanon and I decided to continue my training in France by enrolling in the Master       ACSYON. I found this formation to be very complete. The instructors are experts in their scientific    domains and always available to answer students’ questions. I did my internship at the XLIM laboratory with prof. Adly and then enrolled in the PhD program, to work on complementarity problems. The Master ACSYON gave me an effective training in optimization, which has proved to be crucial for my research work. I am now in my third year as a PhD student. My scholarship is funded by a doctoral contract. I have also taken up teaching duties, which allow me to make my first steps in the field of higher education. I am very happy with my choice of studying in Limoges. Life here is very pleasant. In conclusion, I am highly satisfied with the Master ACSYON, which gave me solid bases to enter the world of scientific research. omheni Riadh, class of 2011 After obtaining a first-year master’s degree in Mathematics and Computer Science, I wished to acquire more specialized knowledge in optimization. For this reason I enrolled in the second-year ACSYON program in 2010-2011. I took part in theoretical and practical courses, gave oral presentations and attended high-level lectures offered by renowned speakers. I did my internship at ENSEEIHT in Toulouse, where my advisor was one of these external instructors. During this six-months internship I had the opportunity of applying the knowledge I had acquired: in fact, I developed a new method and heuristics for minimizing the energy required by an electric vehicule. I am now a PhD student at the XLIM laboratory, thanks to a doctoral contract. My advisor is prof. Armand. The topic of my thesis is the design of primal-dual methods for semi-definite nonlinear optimization. jalouli Achref, class of 2012 During my first-year master studies, I followed online courses of numerical optimization and PDEs given by teachers at the University of Limoges. This was my first approach to applied mathematics, since my bachelor degree is in pure mathematics. The following academic year, 2011-2012, I enrolled in the Master ACSYON. Here I could apply my theoretical knowledge to solve problems in technology, physics and engineering. At the end of the master, I went to Germany to do an internship at the University of Duisburg-Essen. The training offered by the Master ACSYON is diverse, rich and complete. It provides effective tools in numerical computation and computer algebra for solving scientific problems. Since September 2012 I am a PhD student at the University of Limoges, with a doctoral contract that includes teaching duties. My research work is done at the XLIM laboratory under the supervision of prof. Barkatou. Moreover, I teach at the Department of Mathematics. I am happy with my choice and I definitely encourage prospective students to apply for the Master ACSYON.
