+It demonstrates a numerical method for computing the optimal event-based sampling
+scheme for the continious-time LQG problem. The problem is related to an elliptic
+convection--diffusion type of partial-differential equation (PDE) with free 
+boundary, a so called Stefan problem. The solution to this PDE is a value
+function $V$, from which the optimal sampling scheme can be determined.
