DESCRIPTION:<span>Many problems in materials science and biology involve p
 articles interacting with strong\, short-ranged bonds\, that can break and
  form on experimental timescales. Treating such bonds as constraints can s
 ignificantly speed up sampling their equilibrium distribution\, and there 
 are several methods to sample subject to fixed constraints. We introduce a
  Monte Carlo method to handle the case when constraints can break and form
 . Abstractly\, the method samples a probability distribution on a&nbsp\;<i
 >stratification</i>: a collection of manifolds of different dimensions\, w
 here the lower-dimensional manifolds lie on the boundaries of the higher-d
 imensional manifolds. We show several applications in polymer physics\, se
 lf-assembly of colloids\, and volume calculation. </span><br><br><br><br><
