[Haskell-cafe] Rather off topic: An ab initio universe simulation?

2010-12-09 Thread Ketil Malde
In order to simulate nature, you need to have the mutation and selection process itself be part of the programs (and not the interpreter). How about you have a world consisiting of some memory, bombard this world with cosmic radiation, and add some enzymatic activity in the form of an

Hi Ketil, In order to simulate nature, you need to have the mutation and selection process itself be part of the programs (and not the interpreter). Hence the interpreter can itself be modified? How about you have a world consisiting of some memory, bombard this world with cosmic radiation,

You can do all sorts of fun things with computers. Assuming that you are interested in modeling really real life, how will you estimate parameters (e.g. mutation rates) based on real data? How will you quantify whether this a good or a bad model? I think living in a fact-free world is a bit

The good fact about evolutionary simulations is that all is theoretically possible . The bad fact is that in practice is very hard to achieve results. Biota.org has links to some artificial life projects.Some of them are naive, but some others may be interesting. http://www.biota.org/

Have you read: Fontana Buss : What would be conserved if 'the tape were played twice'? in PNAS? It's quite fun - they model chemical reaction as alpha-reduction in the lambda calculus and look at evolution. Tom On Thu, Dec 9, 2010 at 10:15 PM, Ketil Malde ke...@malde.org wrote: Michael Lesniak
