Lattice-based algorithms in practice Are there any applications of lattice-based algorithms other than those in cryptography and integer programming?

Could someone state a few papers where 
the primary algorithms use lattice-based LLL algorithms?
If you look at the original paper by Lenstra, Lenstra, and Lovasz, you will see the following applications:


factoring univariate polynomials over the rationals (the motivation for developing LLL basis reduction)
efficient version of Dirichlet's classical diophantine approximation theorem: for rationals $a_1, \ldots, a_n$ and $\epsilon$, find in polynomial time integers $p_1, \ldots, p_n$, and $q$ such that 


$$
\forall 1 \leq i \leq n: |qa_i - p_i| &lt; \epsilon,
$$

and $q&lt; 2^{n(n+1)/4}\epsilon^{-n}.$ Dirichlet proved this without the $2^{n(n+1)/4}$ factor, but his proof is a pigeonhole argument (sometimes called Dirichlet's principle) and does not yield an efficient algorithm.


efficiently find integer relations between rationals: given rationals $a_1, \ldots, a_n$ find integers $m_1, \ldots, m_n$ such that $\sum{m_i a_i}$ is minimized and the $m_i$ are not too large.


You can also check out Oded Regev's lecture notes which reference more applications. This book chapter by Hanrot gives details about quite a few applications of LLL to constructive versions of results in diophantine approximation.
