Century Dictionary and Cyclopedia
    • n roulette An engravers' tool, used for producing a series of dots on a copperplate, and in mezzotint to darken any part which has been too much burnished. Roulettes are of two kinds: one is shaped like the rowel of a spur; the other has the rowel at right angles with the shaft, thick in the middle and diminishing toward the sides, which are notched and sharpened to a series of fine points. A similar instrument is used in mechanical drawing, and in plotting. It is dipped into India ink, so that the points imprint a dotted line as the wheel is passed over the paper.
    • n roulette A cylindrical object used to curl hair upon, whether of the head or of a wig.
    • n roulette In geometry, a curve traced by any point in the plane of a given curve when this plane rolls on this curve over another curve.
    • n roulette A game of chance, played at a table, in the center of which is a cavity surmounted by a revolving disk, the circumference of which is generally divided into 38 compartments colored black and red alternately, and numbered 1 to 36, with a zero and double zero. The person in charge of the table (the banker or tailleur) sets the disk in motion, and causes a ball to revolve on it in an opposite direction. This ball finally drops into one of the compartments, thus determining the winning number or color. The players, of whom there may be any number, may stake on a figure or a group of figures, on even or odd number, or on the black or red. Should the player stake on a single figure and be successful, he wins 35 times his stake. The amount varies in the event of success on other chances.
    • roulette To mark with dotted lines with a roulette.
    • roulette To perforate with a roulette or similar instrument, as in preparing blank checks, for ease and convenience in removal from a stub, or sheets of printed postage-stamps for the separation of the stamps, the one from the other, when needed.

    • n Roulette rōōl-et′ a little ball or roller: a game of chance played on an oblong table divided into numbered and coloured spaces, and having in the centre a rotating disc on which a ball is rolled until it drops into one of the spaces, the player winning if he has staked his money on that space or its colour: an engraver's tool: a cylindrical object used to curl hair upon:
    • n Roulette rōōl-et′ (geom.) a particular kind of curve.

In science:

He suggests the perdurantist, or at least the advocate of Humean supervenience, should say that even for a inhomogeneous disc like a roulette wheel, there is nothing ob jectively right about defining persistence in terms of “tracking” spatially varying qualitative features such as one of the wheel’s numerals.
On the Persistence of Homogeneous Matter
Features in the ensemble of histories include “roulette tra jectories”, with longlasting inflations in the direction of the rolling axion, enhanced in number of e-foldings over those restricted to lie in the τ -trough.
Roulette Inflation with K\"ahler Moduli and their Axions
Some of the tra jectories are predominantly θ ones before settling into a τ -valley, similar to a roulette ball rotation before locking into a slot with a specific number, hence the name roulette inflation.
Roulette Inflation with K\"ahler Moduli and their Axions
These roulette wheel tra jectories have an enhanced numbers of e-foldings relative to pure τ tra jectories.
Roulette Inflation with K\"ahler Moduli and their Axions
To the extent that these single-inflaton estimations are reasonable, we again found plenty of roulette tra jectories exist which satisfy the CMB+LSS data.
Roulette Inflation with K\"ahler Moduli and their Axions
Here it is the mod operation that introduces some randomness by mimicking the circular arrangement of a roulette wheel.
Random Number Generators: A Survival Guide for Large Scale Simulations
Early approaches: coin flipping, rolling of dice, roulette.
Random Numbers in Scientific Computing: An Introduction
Note that this is similar to a roulette where a croupier spins a wheel with 37 pockets in one direction, then spins a ball in the opposite direction around a tilted circular track running around the circumference of the wheel.
Random Numbers in Scientific Computing: An Introduction
His scrambling procedure is designed to destroy any nascent correlations that might exist in the original bit stream of measurements, without introducing any extra correlations of quantum-mechanical origin (hence his use of the classical roulette-wheel).
Quantum Mechanics and Algorithmic Randomness
Selection is based on ranking rather than absolute fitness, and makes use of the Roulette Wheel algorithm.
Computational Asteroseismology
To illustrate the selection mechanism, it is instructive to think of a roulette wheel in which the size of the different fields is proportional to the fitness.
Stochastic evolutionary game dynamics
For instance, Chapter 9 of (Sornette, 2003) suggests a number of options, including the “statistical roulette”, Bayesian inference and error diagrams.

There are several different models in this class including K¨ahler inflation, Roulette inflation and Fibre inflation which all have exponential potentials.
Towards an Observational Appraisal of String Cosmology
Both K¨ahler and Roulette inflation lead to small tensor models r ∼ O(10−10 ), with the simplest K¨ahler model having the form V = V0 (1 − e−aφ ), and hence leads to ns = 1 − 2/N ∗ (this corresponds to the p = −∞ small field example of Section 2.1).
Towards an Observational Appraisal of String Cosmology
In Roulette models the inflaton is associated with a classical tra jectory through field space (perpendicular to the isocurvature tra jectory) .
