NDb -(60% x Nc/Nt +40% x Dc/Dt) x 17,585
"Mathematicians called in by the Metropolitan Police think they have worked out the best way to beat crime in the capital."
Are there any UK mathematician/cops out there that know what the variables actually are?

(via Ananova)

NDb signifies the number of officers to be allocated to each borough.

The formula allocates 60% of officers according to a borough's need, which includes factors such as day-time and night-time population, unemployment and economic deprivation.

Nc is the need of a specific borough, and Nt is the need score across the whole of London.

The remaining 40% of officers are allocated according to the level of crime or demand.

Dc is the demand in a specific borough, and Dt the total demand.

The total number of officers available is 17,585.

Oh, and the original posted formula is incorrect, it's NDb=, not NDb-.

``It does have a very practical application. It isn't just something some mathematician's cooked up in a laboratory.''

ah, with well defined concepts like "need" and "demand" this is just so darn trivial. now the cops will have no problems whatever! just work out "need" and "demand " real quick each night, and you're done.

Let us represent each piece of lab equipment (including chemicals) with a certain chemical reaction. For example, the Erlenmeyer Flask will be represented by oxidization, the bunsen burner by combustion, and so forth. It is then obvious that we can represent any experiment as a series of unique chemical reactions. The series which represents burning something with a Bunsen Burner is, of course, the flame of the Bunsen Burner itself. We leave the remainder of Goedel's Laboratory Incompleteness Proof as an exercise to the reader.

This may just be me, but I've never seen a % symbol in any respectable equation. I've seen a decimal point on the other side, but never a % symbol. Is this because the equation was dumbed down for the police, or was the dumbness a little farther up-stream?

Ah, I knew there had to be some good reason why I could never prove that danged Riemann Hypothesis, but now I know: Not enough chemicals!
