A cache dedicated to the Practical Algorithm To Retrieve Information Coded In Alphanumeric - the Patricia Tree. If you're wondering what that is, well, it's a radix tree with radix equals 2. No ? I wasn't any the wiser after reading about it either.
I've taken over ownership of Geoff&Steph's original PAT series, and as you can see I've decided to add a couple of extras to make it back into a completed loop. While I was at it, I decided to change the series to pay homage to a few greater or lesser known Pats.
Well, why not ?
