History of Viennese Workshops
This is the 15th conference in a series of workshops which started 40 years ago. The preceding 14 workshops took place with a more or less three years recurrence time.
The 1st was organized in October 1981. The core topic was the dynamic theory of the firm by means of optimal control theory. The contributions of prominent researchers as A.Bensoussan, N.V.Long, S.Jorgenson and G.L.Thompson illustrate this approach (see Feichtinger, 1982).
The 2nd Viennese Workshop took place in 1984. Since then the spring-date (May, June) was kept. The number of papers presented as well as those of the participants increased substantially, as is illustrated by the second proceedings volume published again by North-Holland (Feichtinger, 1985). Specialists in optimal control theory and differential games, as T.Basar, R.F.Hartl, G.Leitmann, P.Michel, S.P.Sethi, and K.Sydsaeter presented interesting papers. A highlight was E.Dockner´s stability analysis for two-state optimal control models.
Another three years later the 3rd workshop was organized (see Feichtinger, 1988). Among the new contributors were F.Colonius, K.Nishimura and G.Sorger. The main issues of this workshop were persistent stable limit cycles as optimal solutions of economic models.
The 4th workshop took place in 1991. The reason for the one-year delay was that in 1990 a large Central European Operations Research conference was organized in Vienna by the Austrian OR-society jointly with the Swiss and German OR societies. The peer-referred papers were published in Feichtinger (1992). In particular, we refer those of M.Brokate, P.M.Kort, and F.Wirl.
In the nineties, bifurcations and chaotic behavior has become an important topic in dynamic economics. The 5th Viennese Workshop (which was shifted for one day to Bratislava) reflected this growing importance of nonlinear dynamical systems in economic analysis. Among the pertinent contributions let us mention that of C.H.Hommes, T.Mitra, L.Montrucchio, and A.Venditti. A selection of the papers presented was published in Dockner et al. (1998).
The 6th Viennese Workshop was organized in 1997. Optimal control models and differential games applications were published in the Annals of Operations Research (Dawid et al., 1999a). For contributions on nonlinear dynamical systems and adaptive methods compare Dawid et al. (1999b). Among the participants were C.Deissenberg, F.Gozzi, and R.Neck.
The 7th Workshop was held in May 2000. Among the contributors were C.Chiarella, W.Semmler, and J.Hofbauer. Some interesting papers on differential games presented at the meeting were published in Feichtinger et al. (2002). For other economic applications of nonlinear dynamical systems see Dawid et al. (2002). An additional outlet was a special issue of OCAM on optimal control applications (Feichtinger et al., 2001). Moreover, three of the papers presented at this workshop were published in the Essays in Honor of G.Feichtinger, edited by Dockner et al. (2000).
The 8th Workshop was held in 2003. Special attention was paid to multiple equilibria, Skiba points and age-structured (vintage) models using distributed parameter control. Plenary lectures were given by R.Day, E.J.Dockner , F.Clarke, F.Gozzi and H.Maurer.
The 9th Workshop on Optimal Control, Dynamic Games and Nonlinear Dynamics took place in May 2007 in Montreal, organized by Georges Zaccour. Among others, A.Haurie and G.J.Olsder presented two interesting papers.
The 10th Viennese Workshop was held in 2008 at the occasion of the retirement of G.Feichtinger. Only invited papers were presented by G.Leitmann, J.P.Caulkins, G.Sorger, H.Dawid, G.Zaccour, R.F.Hartl, P.M.Kort, F.O.O.Wagener, and E.J.Dockner.
After Bratislava and Montreal not surprisingly the 11th Workshop took place again outside of Vienna. Florian Wagener organized it in spring 2010 in Amsterdam. Important contributions were made by B.LeBaron, W.Semmler and A.Xepapadeas.
A trade-mark of several of the Viennese Workshops was the presentation of optimal control applications for “unorthodox” situations, i.e. planning the “unusual” (compare also Feichtinger and Mehlmann, 1986). To illustrate those models we just mention ̶ aspects of optimal slidemanship, ̶ the economics of everything, ̶ optimal wine consumption, ̶ the Transsylvanian problem of renewable resources (vampirism), and ̶ the dynamics of extra-marital affairs.
The 12th Viennese Workshop was held 2012 in Vienna, with about 230 participants from 31 countries. On four days 184 talks were given, with T.Basar, J.P.Caulkins, E.Dockner, H.Frankowska, A.Haurie, and C.H.Hommes as plenary speakers. Two books (edited by J.Haunschmied, V.Veliov and S.Wrzaczek and by E.Moser, W.Semmler, G.Tragler and V.Veliov) resulted from the workshop and were published by Springer, 2014. They contain selected contributions by participants in the workshop and additionally invited scientists in the fields of dynamic optimization in environmental economics, and dynamic games in economics.
The 13th Viennese Workshop also was organized by ORCOS (TU Wien) and was held 2015 in Vienna, with about 250 participants from 38 countries. On four days 197 talks were given, with A. Bressan, P.M. Cannarsa, H. Dawid, K. Sigmund and G. Zaccour as plenary speakers. Although the title of the 13th workshop was shortened a bit, the scientific topics and the application areas in the last two conferences became considerably broader, including PDE-constrained optimization, stochastic control, mean field control and games, applications in biology, engineering applications.Due to the expansion of the size and the scope of the Viennese Workshop, we decided that it will be more appropriate to call the 14th one “Viennese Conference”.
Continuing the tradition, most recent 14th Viennese Conference was also organized by ORCOS (TU Wien) in the period July 03-06, 2018 in Vienna. The conference was attended by over 300 participants from 37 countries. 268 talks were given in 5 parallel sessions, in addition to the plenary lectures by G. Bock, G. Deffuant, M. Fornasier, H. Schättler, and W. Semmler.
