Comments

The automata starts with 2 entries on each axis of value 3.

Defined value(u,v) for any u,v natural the value of each cell of the automata.

The axis(u,0),(u,-1) and (0,v),(-1,v) are value 3.

Matrix (with entries):

until approximately at a(300), when it disappears, and form a more chaotic structure that covers all the area of (u+175,v+175).

Examples

			value(1,1) = floor(((3)+(3)+(3)+(3)+(3)+(3)+(3))/7 +1) = 4,
value(1,2) = floor(((4)+(3)+(3)+(3)+(3)+(3)+(3))/7 +1) = 4,
value(2,1) = floor(((3)+(4)+(3)+(3)+(3)+(3)+(3))/7 +1) = 4,

Formula

value(v,u)= (In order of priority)

if( (v,u-1)+(v-1,u)+(v-1,u-1)+(v,u-2)+(v-2,u)-(v-1,u-2)-(v-2,u-1) )>10;0

if( (v,u-1)+(v-1,u)+(v-1,u-1)-(v,u-2)-(v-2,u) )=5;3

if( (v,u-1)+(v-1,u)+(v-1,u-1)+(v-1,u-2)+(v-2,u-1)-(v-2,u-2) )=3;2

if( (v-1,u-2)+(v-2,u-1)+(v-2,u-2)+(v-1,u-1)-(v,u-1)-(v-1,u) )=1;1

if nothing= floor(((v,u-1)+(v-1,u)+(v-1,u-1)+(v,u-2)+(v-2,u)-(v-1,u-2)-(v-2,u-1))/7 +1)
