Lines: 32 Nntp-Posting-Host: sapphire I tried cell-automata simulation (life), and tried to find the rule between micro-informations and macro-informations. micro-informations mean "the state of cells (0 or 1)". macro-informations mean "ration of firing cells".I tried life and got many data,and plot date.(by using S language.) Then I want to evaluate the result of experiment.here there is some problens and questions. 1. space of state is very large.(10*10 lattice --> 2**100 state). so,I can't try all states.For example I try 10000 states,10000/2**100 equals fairly 0.0000..... To evaluate the result how many traial is enough? 2.The interesting problem is the limit of states.(equiblibram states).How many equiblibram states in 10*10 lattice? I wan`t to know "the number of equibliam states" correctly.If it is imposible,how can I estimate it? 3.I want to know the distribution of states.(there are 2**100 states,and the distribution of states depends on time.) 4 I hear that existence of "pattern of eden".It can`t bee seen except the init-state.How many "eden" exist? 5 I need the mathematical-model for cellular-automata.for example, marcov chain.Can anyone describe life,mathematically? 6 If you define cellular-automata,how do you define? takashi kido kido@nak.math.keio.ac.jp
