Hello everyone,
Who could be useful for this problem. I am a biologist and in my ecology
researches I try to forecast what the evolution in the number of animal
species will be provided there is an interrelation with other living
organisms. Example: In a pond we find 4 species of living organisms :
A, B, C, D, In monthly surveys we observe if their number increased,
decreased, or remained constant thus assessing them respectively 1, 2,
X. After 10 observations the result will be: 1 1 1 2 1 2 1 X X 2   for
specie A
2 1 1 1 2 1 1 2 1 2    for            B 1 2 1 X 1 2 2 2 1 1    for      
C 2 1 2 1 1 2 1 2 2 2    for            D

What would the next sequence of number will be ? There always is a law
which is non-visible to the eye but identifyable through a system. Is
there a software available able to work this out ?. Thanks. Marco
