Mitigation and Herd Immunity for Covid-19 Is Likely to Fail and Distributed Consensus Optimization Becomes Relaxed

Abstracts:

[nur in Englisch verfügbar]

Mitigation and Herd Immunity for Covid-19 is Likely to Fail: 
Based on microsimulations, we show that the mitigation interval for Covid-19 is too small for fine-tuned measures imposed by decision makes. We show how an effective testing strategy together with mild social distancing can lead to an extinction of the disease. Furthermore results of the prevalence and its dependence on the time delay in back-tracking are provided. Moreover first results for school openings, the „tracking app“ and economic consequences are given.

Distributed Consensus Optimization becomes relaxed 

Consensus optimization problems arise in many engineering applications.
Some examples include Machine Learning, Smart Grids, Wireless Sensor Networks, economic power dispatching problem, and Distributed Model Predictive Control (DMPC). During the past decades, various distributed numerical algorithms were proposed to solve the consensus optimization problem. The ADMM is among the most widely used and efficient algorithms for solving this class of distributed problems. As the name suggests, this algorithm is characterized by the alternating solution of two optimization sub-problems, and an update of the Lagrange multipliers.

This division of the computational burden in two distinct steps makes the ADMM a computationally efficient algorithm, particularly when applied in distributed scenarios characterized by agents with reduced capabilities. Many improvements in ADMM have been presented in the last years, including the Relaxed Hybrid ADMM (RH-ADMM) proposed in 2019. In the present seminar, some important ADMM algorithms will be reviewed and the RH-ADMM will be discussed in detail.

  • Mechatronics in Mechenical and Automotive Engineering (Dep. of Mechanical and Process Engineering)
  • Automation Control (Dep. of Electrical and Computer Engineering)
  • Electromobility (Dep. of Electrical and Computer Engineering)

The seminar takes place at the ITWM every 1st Tuesday of a month (besides holidays and summer break). Aims are broadening of experiences and exchange of scientific views – also beyond the organizing groups.

Typical subjects of talks are:

  • ongoing or recently finished graduations and doctoral theses
  • current research and projects

The topics vary from mathematical methods to technical implementations. Usually, the talks present research results. However, some show open issues for brainstorming and inputs from the audience.
