Query: A stochastic approach to the reconstruction of spectral functions in
  lattice QCD   We present a Stochastic Optimization Method (SOM) for the reconstruction of
the spectral functions (SPFs) from Euclidean correlation functions. In this
approach the SPF is parameterized as a sum of randomly distributed boxes. By
varying the width, location and height of the boxes stochastically an optimal
SPF can be obtained. Using this approach we reproduce mock SPFs fairly well,
which contain sharp resonance peaks, transport peaks and continuum spectra. We
also analyzed the charmonium correlators obtained from $N_{\tau}$=96, 48, 32
lattices using SOM and found similar conclusion on the dissociation
temperatures of charmonium ground states as that obtained using the Maximum
Entropy Method.
