A Successive Linear Relaxation Method for MINLPs with Multivariate Lipschitz Continuous Nonlinearities
Julia Grübel, Richard Krug, Martin Schmidt +1
We present a novel method for mixed-integer optimization problems with multivariate and Lipschitz continuous nonlinearities. In particular, we do not assume that the nonlinear cons…

Nonlinear Optimization of District Heating Networks
Richard Krug, Volker Mehrmann, Martin Schmidt
We develop a complementarity-constrained nonlinear optimization model for the time-dependent control of district heating networks. The main physical aspects of water and heat flow…
