). Its goal is to choose a place to apply an actuator in a given area depending on time. We consider a rectangle $\mathrm{\Omega }=[0,1]\times [0,2]$ with the boundary $\partial \mathrm{\Omega }$ and the time horizon $T=[0,10]$ as the domains. The objective function is quadratic, its first term captures the desired final state $\overline{u}\equiv 0$, 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.
