Its goal is to choose a place to apply an actuator in a given area depending on time.
We consider a rectangle ![\Omega=[0,1]\times[0,2]](https://mintoc.de/images/math/b/9/e/b9e9ecbd1ca99669f6d13a62bcf6142b.png)
with the boundary 
and the time horizon ![T=[0,10]](https://mintoc.de/images/math/0/a/e/0aef63dc3199780b7093eeb4bd8d74f5.png)
as the domains.
The objective function is quadratic, its first term captures the desired final state 
, the second term regularize the state over time and the third term regularize the continuous controls.
The constraints are a source budget, which limits the quantity of placed actuators, and the two-dimensional heat equation with some source function.
Additionally, we assume Dirichlet boundary conditions and initial conditions.
