15, 21, 27, 33... Add 6 to the previous number S n = S n-1 + 6 Examples of sequences 1, 3, 9, 27, 81, 243... Multiply the previous number by 3 S n = 3*S n-1 The Fibonacci Sequence Start with the numbers 1 and 1, and apply the following rule: S n = S n-1 + S /n-2 In other words, the next term is found from adding up the previous 2 numbers The First Few Fibonacci Numbers 1, 1, 2, 3, 5, 8, 13/

To find any given term we have to know the value of the previous two terms. We can write/

00011 00100 00101 10 Amortized analysis (Cont.) On the worst case increment takes O(k). k = #digits What is the complexity of a sequence of increments (on the worst case) ? Define a potential of the counter: Amortized(increment) = actual(increment) +   (c) =/cascading cuts)  (decrease-key) = O(1) - #(cascading cuts) ==> amortized(decrease-key) = O(1) ! 49 Fibonacci heaps (analysis) Cascading cuts and successive linking will pay for themselves. The only question is what is the maximum degree of a node/
