coondoggie brings us a NetworkWorld story about IBM's efforts to use complex algorithms to manage responses to natural disasters. Researchers are making use of recent increases in processor speed and algorithm efficiency to develop a scalable, flexible model capable of handling the complicated planning involved in reacting to a crisis. Quoting:
"'We are creating a set of intellectual properties and software assets that can be employed to gauge and improve levels of preparedness to tackle unforeseen natural disasters,' says Dr. Gyana Parija. 'Most real-world problems involve uncertainty, and this has been the inspiration for us to tackle challenges in natural disaster management.' In the case of flooding, for example, the stochastic programming model would use various flood scenarios, resource supply capabilities at different dispatch locations, and fixed and variable costs associated with deployment of various flood-management resources to manage various risk measures. By assigning probabilities to the factors driving outcomes, the model outlines how limited resources can meet tomorrow's unknown demands or liabilities. In this way, the risks and rewards of various tradeoffs can be explored, IBM said."

Heckuva job, Brownie! More optimistically, I hope that their algorithms could predict the 4 or 5 "wild"- fires in Southern California which are all started mysteriously(on the same day) "in season."

Shouldn't be too hard. One of the things they discovered while studying line noise in telephone circuits is that the cause of the noise doesn't matter: it could be induction from nearby motors, bad connections influenced by the wind, or short-circuits triggered by someone dropping a screwdriver -- it all fits into the statistical patterns. In the case of fires, it doesn't matter if it's lightning, arson, or volcanic eruption, the pattens still hold.

Awesome, now they get to patent how to respond to natural disasters so that no one else can innovate... another victory for our wonderful patent process!

The new thing with this apparently is that they're using a new mathematical model that previously was too computationally expensive to do on a large scale. Computers are powerful enough to use these models now.

But then it goes on to talk about mostly foreseeable natural disasters. If you live on a flood plain or a low-lying coastal area subject to hurricanes, you're going to get flooded. In an earthquake zone you're going to get earthquakes. Lot of vegetation in an area that has dry spells, fires. And so on.
Legitimately unforeseen natural disasters would be things like a comet impact [imdb.com], volcanoes erupting in downtown LA [imdb.com], or perhaps alien invasion [imdb.com]. Oh wait, that last would be an unnatural disaster, wouldn't it? But come to think of it, the ones I just mentioned have all been foreseen too.
I guess I just don't foresee a need for this software. Maybe they should work on software for foreseeable disasters.

What I do remember though, is that I mentioned to my superiors that a case-based reasoning engine would take a lot of the (non-discrete) math out of the whole thing. Because things happen and we learn from them. Has the nature of nature changed, or was I wrong in the first place?

Many research groups are working on simulation and prediction of behavior, natural disasters, preparedness, etc. But the first words out of an IBM researcher's mouth are "intellectual properties and software assets".
Shame on you.

Re:Complex math? (Score:5, Informative)
In mathematics, "complex" does not mean complicated any more than "proper" means correct or "rational" means sane or "group" means any old gathering or collection. These words have very specific meanings in mathematics, and using them for their general-English meaning, in the context of math, is at best confusing and at worst outright misleading.
You can talk about a "complex algorithm", and people will generally understand you mean a complicated one, because the word "algorithm" lends more of a computer-science context. You can say "complex way of doing things" and convey the idea of complicatedness, because "way of doing things" is sufficiently general that it doesn't really imply any particular context at all. But saying "complex math" very much conveys the idea of the use of complex numbers (i.e., numbers with a real part and an imaginary part, either or neither or both of which may be zero for any given number) because the word "math" strongly implies a mathematics context and draws the math-jargon sense of the word "complex" to the forefront. Only someone who doesn't *know* what the word "complex" means in mathematics would think of any other meaning.
It's like saying "hedge fund" and expecting people to get the idea that you're collecting money for shrubberies. Only someone with no idea what a hedge fund is would get that impression.

Thus the reason why they are with IBM doing analysis using stochastic modeling is because they failed in the financial industry. They did not improve returns and thus needed another industry that they could tap for money.
