\* Any Wolfram elementary CA in 6D eucl. Neumann CA grid emulator generator *\

\* Written and converted to *LP format by NASZVADI, Peter, 2016,2017 *\
\*  <vuk@cs.elte.hu> *\

\* Standalone version; GMPL version is in wolfra6d.mod *\

\* This model looks up for a subset of vertices in 6D euclyd. grid, *\
\* which has the following properties: *\
\* 1. each vertex' coordinate pairs' difference is at most 1 *\
\* 2. contains the vertices in the main diagonal of the 6d space *\
\* 3. connecting with directed graph edges from all selected vertices  *\
\*    to all selected ones with greater coordinate sums with *\
\*    Hamming-distance 1, the following in-out edge numbers are *\
\*    allowed: (3,6), (1,2), (2,3), (1,2), (4,1), (3,1); according to *\
\*    the mod 6 sum of the coordinate values *\
\* 4. Only vertices of the unit cube's with {0,1} coordinates are *\
\* calculated, but the other cells could be obtained via shifting. *\
\* Assume that the grid is a 6dim. cellular automaton grid with Neumann- *\
\* -neighbourhood, now construct an outer-totalistic rule that emulates *\
\* W110 cellular automaton on the selected vertices: *\
\* Suppose that the 1D W110 cellspace cells are denoted with signed *\
\* integers. Every 1D cell is assigned to (at most "6 over 2") selected *\
\* vertices where each coordinate sums are the same with the integer *\
\* assigned to the origin cell in the domain, they must have the same *\
\* value. Rule-110 means that cell's value is being changed only when its *\
\* neighbours are: (1,1,1), (1,0,1), (0,0,1), other cells remain unchanged. *\
\* Let's denote the default cellstate with "2" in the 6D automaton, and *\
\* the remaining 2 states with "0" and "1" respectively, which correspond *\
\* with the states in W110. The selected vertices must be 0 or 1 of course, *\
\* and the others are "2". *\
\* Now, the transition rule for emulating W110 is the following: *\
\* (x),{1,1,1,1,1,1,1,1,1,2,2,2}->(1-x), x!=2, *\
\* (x),{1,1,1,2,2,2,2,2,2,2,2,2}->(1-x), x!=2, *\
\* (x),{1,1,1,1,2,2,2,2,2,2,2,2}->(1-x), x!=2, *\
\* (x),{1,1,1,1,1,2,2,2,2,2,2,2}->(1-x), x!=2, *\
\* (1),{0,0,0,1,1,1,1,1,1,2,2,2}->(0), *\
\* (1),{0,1,1,2,2,2,2,2,2,2,2,2}->(0), *\
\* (1),{0,0,1,1,1,2,2,2,2,2,2,2}->(0), *\
\* (1),{0,0,0,0,1,2,2,2,2,2,2,2}->(0), *\
\* (1),{0,0,0,1,2,2,2,2,2,2,2,2}->(0); *\
\* notation: (old state),{old neighbours - all permutations}->(new state) *\
\* Other states won't change between two generations. And is known that W110 *\
\* is Turing-complete. So there is a universal CA rule in 6+D eucl. gridS *\
\* Result is in x****** binary variables (total 44 among the 64) *\
