| Title: Are Frogs Turing Compatible?     |
| Speaker: Don "The Lion" Knuth           |
|                                         |
| ABSTRACT                                |
|                                         |
| Several researchers at the University   |
| of Louisiana have been studying the     |
| computing power of various amphibians,  |
| frogs in particular. The problem of     |
| frog computability has become a         |
| critical issue that ranges across all   |
| areas of computer science. It has been  |
| shown that anything computable by an    |
| amphi- bian community in a fixed-size   |
| pond is computable by a frog in the     |
| same-size pond -- that is to say, frogs |
| are Pond-space complete. We will show   |
| that there is a log-space, polywog-time |
| reduction from any Turing machine       |
| program to a frog. We will suggest      |
| these represent a proper subset of      |
| frog-computable functions.              |
|                                         |
| This is not just a                      |
| let's-see-how-far-those-frogs-can-jump  |
| seminar. This is only for hardcore      |
| amphibian-computation people and their  |
| colleagues.                             |
|                                         |
| Refreshments will be served. Music will |
\ be played.                              /
