in reply to Play and win the word morph game with the help of Perl :)

I was asked for the explanation of how my algorithm works. I found in Wikipedia that it's called bidirectional search but when I wrote the script i didn't know its name :) The idea is better explained in WP than I can do it here :)

I run two simultaneous searches: one forward from the source word, and one backward from the target word, and stop when the two trees meet.

    Ieronim,
    This is the very idea (I didn't know it had a name either) I had this morning before coming into work. After converting DBM::Deep over to Storable though, I found all the speed boost I needed and didn't explore it. I know you said in a /msg that you will try to play with a variant using the precompiled datastructure - so will I.

    Cheers - L~R

[Corion]: No. It's just that I'm comparing the same output file twice, instead of comparing the output files of the two runs %-)
[Corion]: Lo and behold, running a program with the correct input files yields the correct (and expected) output. Yay me.
[1nickt]: Got a MacBook and am expected to develop directly on it, ironic given the recent thread about that.
[marto]: Corion, some not too serious issues with the kids, hopefully, other than that just dealing with commuting by car again in the winter, not much fun so far, and there's no real 'bad' weather yet :)
[marto]: 1nickt, glad to hear it, I'm sure you'll bring improvements to their stack in due course ;)
[1nickt]: Just trying to adjust to a new culture. Better doc than I am used to , but quite a bit more Agiley meta-bullshit; at least half a dozen meetings a week, strict "sprint" schedule etc. I'll adjust. And I hope to just switch off after the "scrum" each day at
[1nickt]: ... the end of the afternoon. marto How are you, snowed in? Mum and Dad expecting snow today in Surrey. (Have 5" on the ground here in NJ. And my son's high school in SOCal closed until after Xmas due to fires.)
[Corion]: 1nickt: In a sense the meta-bullshit might even be beneficial to you as you get to hear the cow-orkers talk (or not talk) about the issues you perceive. I think Agile is mostly about the meta ;)
[Corion]: 1nickt: On Sunday maybe 10cm of snow fell, and the airport closed, and the trains stopped running etc :) It always comes as a surprise that snow falls here during the winter...
[marto]: 1nickt, no snow, just some ice on the roads and the usual idiocy associated with humans and driving in less than ideal conditions
