Dear Sirs:
I have a function whose output is of the form {{a,b,c},{d,e,f},k}
That is, a list of length 3, of which the first two parts are lists and the last part is a number
Now, I want to iterate it, with the following termination criterion: stop if the first two parts of the output are identical in two successive runs.
The intuitive (or naively intuitive if you want) way of attacking the problem, I think, is the following:
NestWhile[f,startinglist,UnsameQ[{#[[1]],#[[2]]}&,2]
But it does not work.
What is the solution?
