5.3: Strong Induction vs. Induction vs. Well Ordering

WebbMathematical induction plays a prominent role in the analysis of algorithms. There are various reasons for this, but in our setting we in particular use mathematical induction to prove the correctness of recursive algorithms.In this setting, commonly a simple induction is not sufficient, and we need to use strong induction..

Example 4 Consider the sequence deﬁned by b(0) = 0 b(1) = 1 b(n) = b(jn 2 k) +b(ln 2 m), for n ≥ 2. If you look at the ﬁrst ﬁve or six terms of this sequence, it is not hard to come up with a very simple guess: b(n) = n. We can prove it by strong induction. how many people can play terrariaWebbHere is an example. Proposition 1 Pn i=1(2i¡1) =n2for every positive integer n. Proof:We proceed by induction onn. As a base case, observe that whenn= 1 we have Pn i=1(2i¡1) = 1 =n2. For the inductive step, letn >1 be an integer, and assume that the proposition holds forn¡1.
