everyone,

ever wonder why there isn't more of an effort in the sudoku community to bring all the different names of multicoloring ( skyscraper, kite, x-wing, etc) under one name? it was pointed out in a couple posts by Asellus and others that some confusion might be in the different names used.

when I first read this forum, I was very confused at all the names given to one technique. until I found out it was actually all ONE technique.

same goes for xy-wing and xy-chain because all xy-wings are the simplest form of an xy-chain.

so why isn't there more of an effort to educate that fact?
why is it accepted to keep 3 names for one technique?

sounds like my dad, we never use his real name... his family calls him Sam ( his middle name) his relatives call him Tio ( uncle ), and to top it all off, his freinds call him by his real first name. go figure.

I realize that once a nickname sticks, it sticks. and for some people its how they see the technique that gives it it's name. but that is kind of my point. it needs to be explained.

don't mean to get all deep, just some questions.

In some cases this comes about because there are multiple forums, many with their own names for things.

More importantly, though, there are different levels at which you might visualize the problem.

You discover water, then you find it is dihydrogen oxide, then you discover it is made up of a particular arrangement of protons, neutrons, and electrons, then you discover those can be broken down yet further.

Hence, sky-scrapers are turbot fish which are x-cycles which are AICs. XY-wings are xy-chains which are AICs, too.

The deeper you go, the more you can connect together and the more you can predict; but you don't throw out the term "water" just because you find out it is dihydrogen oxide . After all, in some way "water" represents the real experience far more closely than any deeper terms can.

I like your post, Myth ! I was going to say, the different names add color, but your explanation hits the spot much better. As with scientific and trivial names, the naming depends both on the point of view and the audience. Now that I think of it, I usually say "coloring elimination", because that's how I looked at the grid in the first place. I tend to avoid "kite" and such - but then I never went looking for those specific patterns but any pattern in a single candidate.
