@@ -18,3 +18,24 @@ maybe if i directly pass references to prev and current,
and manually set 'prev' to target new it will be collected?
and then elements after these steps <em>26501365</em> would fit into memory?
** i guess maybe it would help if i had 'fully saturated' field
as my minimal 'skipping' thing
** so. store FieldCoord(fieldRow, fieldCol) for fields which were fully saturated at current step.
filter out neighbors, no need to enter fully saturated fields
when counting
on odd - around the S, on even - with S
but the neighboring fields would potentially (likely?) be in different phases
but i guess they are necessarily in different phases?
or. if width odd - necessarily
if width even - then what?
then S is not in the center
my input is 131 chars of width.
so neighboring are necessarily of different phase.
could compute phase of (0,0)
and adjust from that
