The solving of the problem has been particularly interesting, not only because 5000 changes is on the threshold of attainability in the method, but on account of the importance of palindromes in surprise major composition which has been endorsed.
The increase in the number of CRUs in a peal, from 62 of the full Middleton's to 74 in the peal on page 12, is a notable advance.
The project also helps to bring to a head the problem of authorship of compositions. Does the inanimate computer compose the peal? All thinking people will agree that it does not. But another problem presents itself: who composed the peal, the programmer or the person who made use of the program? The fact is that composing a peal is not a creative activity akin to writing a symphony or a poem - there is a strong impression when one watches a palindromic tree search that peals exist as mathematical possibilities and are merely "discovered" - and the problem may eventually be resolved by changing the terminology.
"This is all!"
