Today's lecture was about solving some problems using Pontryagin's Maximum.

We touched only briefly on controlled diffusion processes. The continuous time model for noise is Brownian motion, $B(t)$. The effect is that the Hamilton-Jacobi-Bellman equation gains another term, in $F_{xx}$.

I mentioned today in connection with section 16.1 (insects as optimizers) that zoologists have observed that in real-world choices of $t_{\text{switch}}$ some insect populations seem to do a good job of predicting $T$ (the time of the serious frost that ends the lives of the workers.) This example is from Luenberger, Introduction to Dynamic Systems, 1979, page 403.
