#### Author's contribution:

#### Greedy optimal control for elliptic problems and its application to turnpike problems

Turnpike theory and greedy algorithms, applied to the steady-state elliptic control problem, are combined to obtain a greedy approximation of parabolic optimal control problems, independent of the initial data

#### Turnpike property for functionals involving $L^1$−norm

We want to study the following optimal control problem...

#### Greedy Control

Control of a parameter dependent system in a robust manner
