Solution to example

Posted by Denis Borris on 24/10/2009, 3:57 pm, in reply to "Re: OK, but..."

Removing the 8 triangles 6,9,10,11,13,15,18,19 leaves:

1[4,16], 2[5,14], 3[7,14], .4[3, 8], 5[1,20] .7[4,8]

8[3,14],12[8,17],14[4, 7],16[3,12],17[2, 7]20[OUT]

Aim is 5[1,20) from where we go to 20[OUT].

Going backwards (move#, triangle#):
6, 20
5, 5
4, 2
3, 17
2, 12
1, 16

So 6 moves.

What looks "difficult" at 1st sight turns out real easy.

Looks like no matter how many triangles you initially put up,
if all works in same manner as this one, then they'll all be
equally easy, except for the "removals", the time to do this
being proportional to number of triangles.
