"notes": "<p><strong>30/09/2102:</strong></p>\n <p>Introduced three functions:</p>\n <p>1. To produce the ranking of a list of 8 numbers.</p>\n <p>2. To produce a list of 8 numbers from a scale of 1..20 which are all distinct.</p>\n <p>3. To produce the maximum of the numbers in a list.</p>\n <p>4. Given an array such as in 2. to find another such array which has max diff between any two corresponding entries less than a given number. This is to ensure that the two array produced do not differ too much, as the point of the exercise is to show that there is a positive high correlation.</p>\n <p> <strong>26/01/2013:</strong></p>\n <p><strong><br /></strong>No advice as yet.</p>\n <p><strong>01/11/2013:</strong></p>\n <p><strong><br /></strong>Changed definition of the variable a so that it does not use the rounded value of b.</p>",
