The New Sudoku Players' Forum

what I've learned from this suduko list is, that people are trying hard
to come up with solving techniques to avoid bifurcation of the
search tree into two possible branches.
They try to eliminate one branch by advanced techniques or lookahead.
Computer-programmers find that this is harder to implement
so they they prefer just calculating some branches and backtracking
over implementing additional techniques.

The problem is that when you are branching in your mind,
you must remember the position from where you branched.
No problem for computers, but humans get confused here.

So, if you were equipped not only with paper and pencil but also
with a quick,good,small,cheap,easy photocopying device ,
would that change your solving strategy ??

Is this maybe a general problem with human thinking which can
be observed in other areas too ?
