Rule:HPP
@RULE HPP
HPP Lattice gas
J. Hardy, O. de Pazzis, and Y. Pomeau (1973) J. Math. Phys. 14, 470.
The earliest lattice gas model. Later made obsolete by the FHP gas on a hexagonal lattice, which has better physical properties.
States following http://pages.cs.wisc.edu/~wylie/doc/PhD_thesis.pdf
Each cell can contain up to 4 particles, each moving in one of the four directions. Outgoing directions SENW map onto 4 bits, so W=0001=1, SEW=1101=13, etc. Next state is simply the collected inputs, in most cases. The exceptions are 5 (EW) and 10 (NS) which get swapped (bounce on collision).
To make the gas useful in Golly's infinite area, I've added reflecting boundary states, 16-31. These work in the same way as gas particles (collecting inputs) but reverse their direction. Contact: Tim Hutton <tim.hutton@gmail.com>
Sink boundary: (or you can vent to the outside but this way is neater) 32 Source boundary: (haven't really worked out how to use this well yet) 33
The HPP gas can also be run using the Margolus-neighborhood emulator in Golly (see e.g. Patterns/Margolus/BBM.rle) but this CA is neater.
