VADOR Events Calendar
We frequently host one off lectures on topics relating to variational analysis, dynamics and operations research. In term-time, we host different speakers at our weekly AKOR seminar. Seminars take place most Thursdays in Sem. R. DB gelb 04. For 25/26 the start-time will move to 4pm. Once a month, the AKOR seminar will be replaced by the Vienna Seminar on Optimization, opens an external URL in a new window - a joint venture with Radu Bot and Yurii Malitskyi of the University of Vienna
We organise the Viennese Conference on Optimal Control and Dynamic Games, typically every three years. VC2025 took place in July 2025. For further details on this conference, and its forerunners, please visit the VC2025, opens an external URL in a new window website.
Topics and speakers for all forthcoming events will be posted below.

AKOR Seminar: Numerical Methods for Solving Pareto eigenvalue complementarity problems
Seminar
We propose to solve Pareto eigenvalue complementarity problems by using interior-point methods. Precisely, we focus the study on an adaptation of the Mehrotra Predictor Corrector Method (MPCM) and a Non-Parametric Interior Point Method (NPIPM). We compare these two methods with two alternative methods, namely the Lattice Projection Method (LPM) and the Soft Max Method (SM). On a set of data generated from the Matrix Market, the performance profiles highlight the efficiency of MPCM and NPIPM for solving eigenvalue complementarity problems. We also consider an application to a concrete and large size situation corresponding to a geomechanical fracture problem. Finally, we discuss the extension of MPCM and NPIPM methods to solve quadratic pencil eigenvalue problems under conic constraints (joint work with Samir Adly and Le Mans Hung.)
