WebFeb 2, 2024 · Solving Recurrence Relations ¶. Recurrence relations are often used to model the cost of recursive functions. For example, the standard Mergesort takes a list of size n, splits it in half, performs Mergesort on each half, and finally merges the two sublists in n steps. The cost for this can be modeled as. T ( n) = 2 T ( n / 2) + n. WebFor example, we may be comparing two arithmetic sequences to see which one grows faster, not really caring about the actual terms of the sequences. In this case, the recursive definition gives the rate of change a little more directly than the standard formula.

WebSolving the recurrence relation: F(n) = F(n-1) + F(n-2) tell us that the time complexity is exponential. We can understand this, by looking at the recursive tree (Figure 2).
