Sorry but theres a problem with the code. For example consider 2nd line of you output. Its giving double probablity in third column (E.E) M6:   M6<-Q, E.E, IV_32 Whereas according to the __DATA__ M6 is coming directly from Q

M6    Q    E

Thus correct output should be :-  M6:   M6<-Q, E, II_15

To give you an intuition this line in data means that the probability of M6 coming from Q is 'E'. That is what I want in third column. If suppose M6 were coming from M76 which in turn comes from Q  M6<-M76<-Q and the input data for these were 

__DATA__
M6   M76   E
M76   Q    E

Then in this case M6: M6<-M76<-Q, E.E, IV_32 would have been a correct output.

So basically the third column is giving wront output, due to which fourth column is also giving incorrect results as it is based on third for its input.
