  The contribution of static and thermal disorder is one of the largest
challenges for the accurate determination of the atomic structure from the
extended X-ray absorption fine structure (EXAFS). Although there are a number
of generally accepted approaches to solve this problem, which are widely used
in the EXAFS data analysis, they often provide less accurate results when
applied to outer coordination shells around the absorbing atom. In this case,
the advanced techniques based on the molecular dynamics and reverse Monte Carlo
simulations are known to be more appropriate: their strengths and weaknesses
are reviewed here.
