The Ecology Of Computation

Broader approaches to computation, from a book with a very suggestive title. This collection of essays inside has been influential to me. In my own research I've been trying to think of computation from different points of view than just the strict Turing machine model, in particular Artificial Life ideas. The ideas here are really helpful, especially the Agoric Computation papers which develop an interesting vision of distributed object computation based on an economic model. The book is hard to find and very expensive. Happily, the Agorics papers are available online.
