Markov chains

What i need is to set a goal, and use markov chains to have the program reach that goal.

For example if i want the program to convey a certain message ie. "i'm hungry" it will use markov chains to say that, once it has reached that goal some sort of checksum will be filled.

needs:
markov chains;
% accuracy counter;
goals.


Goals are created by interactions.

i can have functions contain certain values ie.
"Get me" = 1
"Music" = 2
"name %data" = 3
