hello friends,

yes, i’m definitely here and have intended to get to this. i tried just
now but can’t access the log file in order to link to it. i’ll do that
soon. and a huge congratulations to matt!!! i may have said this before
but i never expected to see anyone beat roice’s solution for years if
ever. you guys consistently surprise me.

i don’t know how i feel about a standardized start configuration.
standardizing definitely makes it a fair start but allows people to
study other people’s solutions in order to find any shortcut between any
pair of positions, which i expect everyone would agree would be unfair.
so there is definitely an advantage to a randomized start so that each
person is on their own but that allows people to generate lots and lots
of starting configurations until they find one that happens to give them
a head start. i’d love to hear everyone to chime in with their suggestions.

and on the subject of jay’s 2^4 solution, i’ve been conflicted about
this because i’m fairly sure that it’s been done before using other
programs (e.g. what
do people think we should do? i’m thinking of adding it to the
hall-of-fame but with a note to this effect.
