random-walk

Are you trying to suggest that the TSA's random-walk approach to "security" actually makes sense in some way?

A 1950 postscript, "Matrix Inversion by a Monte Carlo Method," describes how a statistical, random-walk procedure credited to von Neumann and Stan Ulam "can be used to invert a class of n-th order matrices with only n2 arithmetic operations in addition to the scanning and discriminating required to play the solitaire game."

He had never heard of the random-walk theory of stock pricing.

As I understand it, many of the high-end packages used for mapping circuits into field-programmable logic devices use a random-walk iterative method sharing many features with what we call evolutionary algorithms.

This is how random-walk models of classification work2.

Doing the calculation, this random-walk motion meant that if you had a region about a centimeter in diameter you could keep the atoms corralled for about a second . . .

The random-walk procedure (which, as I've said, is common in cognitive models, as well as neuroscientific ones) thus imputes randomness into the decision making context without having to use an external source (e.g., a dice throw). posted by Chris @ Friday, December 03, 2004

One answer is that classification uses a random-walk procedure a procedure present in several current models of categorization and decision making, as well as neuroscientific models of neuron firings.

Even if both potential options are equally attractive, if we are motivated to choose only one, then using a random-walk model, only one of the options will be chosen.
