Recursion discrete math examples

WebHere is an example. Given any graph G = (V, E), an independent set (of vertices) is a subset I ⊆ V so that no two vertices in I are adjacent. Suppose you wished to count the number of independent sets of a particular graph. In this example, lets do so for the path P10 (i.e., the graph containing 11 vertices and 10 edges arranged in a line).

WebThe most famous example of a recursive definition is that of the Fibonacci sequence. If we let be the th Fibonacci number, the sequence is defined recursively by the relations and . (That is, each term is the sum of the previous two terms.) Then we can easily calculate early values of the sequence in terms of previous values: , and so on. WebExamples for. Recurrences.
