Re: A82: Life


I wasn't aware that there was an 85 version - but I went to ticalc.org
and found it.  It works totally differently than mine does - from what i
could read in the documentation it uses the graph memory as the array,
and then kills or creates life in a cell by counting the number of
neighbors each cell has every generation.  Mine represents each cell as
a byte in the APD_BUF - one bit determining if it is alive, another
determining if it will survive to the next generation, and 4 bits
holding the number of neighbors.  Each time a cell dies or is born, i
simply increment or decrement the number of neighbors of each of the
surrounding cells.  I think it works faster than his algorithm because
it doesn't have to recalculate the number of neighbors every cell has
every generation.  Unfortunately, I don't have access to an 85, so i
can't see if I'm right or not.  As for it being bloated - the size of
his program is approximately 700 bytes (it is 732 bytes before it is
sent to the calculator).  Mine is 635 bytes if you compare the programs
more equally - take the size of the demo program, which doesn't have any
input routines or instructions, and subtract 256 bytes because it
includes a whole sample array.  So, although I know my coding isn't the
most compact or efficient, it isn't that bloated.  If you want, i could
release a version without a title screen or instructions but still with
the input routine - it would be 943 bytes.
