Hello, Seqfans.
Here is another kind of "Almost Integer ".
[Definition of K-sequence] , K for Kimyo which means strange.
a(n)=Floor[A*a(n-1)+B]/p^k , where p^k is the highest power of p
dividing Floor[A*a(n-1)+B] . A,B are real numbers. p is prime.
If the coefficient A is an "Almost Integer", more exactly, A=p^m+e ,
then the K-sequence becomes an "Extremsly Strange Sequence".
Where e is a small positive real number.
The sequences such that {A,p}={4+e,2}, {3+e,3}, {5+e, 5}, {7+e,7}...
seem to belong in the same class of K-sequence.
Only the sequene that {A,p}={2+e,2} is different from the other ESS.
I named it a "LLI", for "a lot of linear parts which are isolated each
other".
It contains also many polynomial sub sequences.
All LLI might be periodic.
I cojectured as follows.
"limit e --> 0 then {period of LLI} --> infinite"
Example :
x0,p,a,b=1,2,2.00001,3.0 period=180492
x0,p,a,b=1,2,2.00013,3.2 period=6366
x0,p,a,b=1,2,2.00013,3.0 period=1790641
x0,p,a,b=1,2,2.0001,3.0 period=13677
x0,p,a,b=1,2,2.001,3.2 period=1670
