Using a coarse molecular-dynamics (CMD) approach with an appropriate choice
of coarse variable (order parameter), we map the underlying effective
free-energy landscape for the melting of a crystalline solid. Implementation of
this approach provides a means for constructing effective free-energy
landscapes of structural transitions in condensed matter. The predictions of
the approach for the thermodynamic melting point of a model silicon system are
in excellent agreement with those of ''traditional'' techniques for
melting-point calculations, as well as with literature values
