Comparison To Simulated Annealing
Quantum annealing can be compared to simulated annealing (SA), whose "temperature" parameter plays a similar role to QA's tunneling field strength. However, in SA the neighborhood stays the same throughout the search, and the temperature determines the probability of moving to a state of higher "energy". In QA, the tunneling field strength determines instead the neighborhood radius, i.e. the mean distance between the next candidate state and the current candidate state.
In more elaborated SA variants (such as Adaptive simulated annealing), the neighborhood radius is also varied using acceptance rate percentages or the temperature value.

Famous quotes containing the words comparison to, comparison and/or simulated:
“It is very important not to become hard. The artist must always have one skin too few in comparison to other people, so you feel the slightest wind.”
—Shusha Guppy (b. 1938)
“The difference between human vision and the image perceived by the faceted eye of an insect may be compared with the difference between a half-tone block made with the very finest screen and the corresponding picture as represented by the very coarse screening used in common newspaper pictorial reproduction. The same comparison holds good between the way Gogol saw things and the way average readers and average writers see things.”
—Vladimir Nabokov (1899–1977)
“Simulated disorder postulates perfect discipline; simulated fear postulates courage; simulated weakness postulates strength.”
—Sun Tzu (6th–5th century B.C.)
