	'''Reptation moves''' are also known as the "slithering snake" model. One [[Random numbers \| randomly]] chooses one of the two ends to become~~, on this occasion,~~ the head of the snake. One then removes a piece of its tail, and after another random selection between freely available sites, one tacks on a new section to become the head of the snake. For example:		'''Reptation moves''' are also known as the "slithering snake" model <ref>[http://dx.doi.org/10.1063/1.431268 Frederick T. Wall and Frederic Mandel "Macromolecular dimensions obtained by an efficient Monte Carlo method without sample attrition", Journal of Chemical Physics '''63''' pp. 4592-4595 (1975)]</ref>. It is particularly useful in [[Lattice simulations (Polymers) \| lattice simulations]] of long chain molecules such as [[polymers]]. One [[Random numbers \| randomly]] chooses one of the two ends to become the head of the snake. One then removes a piece of its tail, and after another random selection between freely available sites, one tacks on a new section to become the new head of the snake. For example:

	<br>:[[Image:Reptation.png\|500px]]<br>		<br>:[[Image:Reptation.png\|500px]]<br>

			If the position of the head is already occupied, the move is rejected. And, in order to avoid any bias, the head now becomes the tail in the next trial move.
