Emergency responders have hard constraints. Dozers and crews need to be moved into place. Aircraft need fuel and access to water or fire retardant. Crew need meals and can only function and survive within certain temperature ranges. The objectives themselves have a political dimension: Save multi-million dollar properties vs. public forests vs. native lands. In this sense the objectives are fuzzy and the whole firefighting effort itself depends on a significant extent to predicting weather conditions accurately. Some of those weather conditions are even created by a fire.
One can cast the constraints as coarse energy levels, but that may wash out the ill-defined objective entirely. -----Original Message----- From: Friam <[email protected]> On Behalf Of u?l? ?>$ Sent: Tuesday, June 1, 2021 10:20 AM To: [email protected] Subject: [FRIAM] heuristics for fuzzy objectives (was Re: Drones to detect wildfires) Another context in which a *softening* of objectives, or perhaps multi-objective orientation, might help: Safety Third https://www.jems.com/operations/safety-is-third-not-first-and-we-all-know-it-should-be/ This context does a better job of highlighting the point that objective-less wandering is *not* unequivocally better than [multi-]objective optimization. Of course, Stanley glosses this in his comments about "modest" objectives. Perhaps we could reframe the idea that an emergency responder's desire to both help someone and not be injured in the process is a "modest" [set of] objective[s]? But it should be easy to see why that's dodgy rhetoric. Staying alive while helping people is "modest"? Really? The "safety first" mantra is not, unlike the strawman set forth in this article, a hard *ordering* of priorities. The mantra is an attempt to get the individual to think dynamically, adaptively. We know your dopamine-fueled risk-taking personality will *cause* you to leap into the fray before engaging your conscious mind. So our (perhaps flawed) attempt, here, is to encourage you to keep your conscious mind engaged and *balance* all the rational priorities you know apply. Stanley's rhetoric was hyperbolic if applied literally, especially to situations in the middle of the spectrum between "modest" and "ambitious". But given the uphill battle, it was useful hyperbole. It was a great shock-jock technique. An "analog" to clickbait. Hook 'em quick. But 5-6 years after peak rhetoric, we should be able to couch it in a reasonable spectrum. Heuristics for when to formulate and solve for crisp objectives versus when to *play* versus a mix of both seem more interesting at this point.
