A SimCity for the Climate

Posted on 27 April 2020 by ecoquant

SimCity is/was a classic simulation game teaching basics of public policy, energy management, and environmental regulation. My kids played it a lot. Heck, I played it a lot. Now, Climate Interactive, Tom Fiddaman of Ventana Systems, Prof John Sterman of … Continue reading →

    I have used dlm almost exclusively, except when extreme efficiency was required. Since Jouni Helske's KFAS was rewritten, though, I'm increasingly drawn to it, because the noise sources it supports are more diverse than dlm's. KFAS uses the notation and approaches of Durbin, Koopman, and Harvey.

    ``The real problem is that programmers have spent far too much time worrying about efficiency in the wrong places and at the wrong times; premature optimization is the root of all evil (or at least most of it) in programming.''
