[LUG.ro Mix] Hot Ice Computer

[Horacio Castellini]

     We experimentally demonstrate that supersaturated solution of
sodium acetate, commonly called 'hot ice', is a massively-parallel
unconventional computer. In the hot ice computer data are represented by
a spatial configuration of crystallization induction sites and physical
obstacles immersed in the experimental container. Computation is
implemented by propagation and interaction of growing crystals initiated
at the data-sites. We discuss experimental prototypes of hot ice
processors which compute planar Voronoi diagram, shortest collision-free
paths and implement AND and OR logical gates.
