Line 1:
The '''Wolff algorithm''', named after [[Ulli Wolff]], is an [[algorithm]] for [[Monte Carlo simulation]] of the [[Ising model]] in which the unit to be flipped is not a single spin, as in the heat bath or Metropolis algorithms, but a cluster of them. This cluster is defined as the set of neighbouring spins sharing the same value of the spin. The Wolff algorithm is an improvement over the [[Swendsen–Wang algorithm]] because it has a larger probability of flipping bigger clusters.
