Strong structural induction
WebStructural induction Assume we have recursive definition for the set S. Let n S. Show P(n) is true using structural induction: Basis step: Assume j is an element specified in the basis step of the definition. Show j P(j) is true. Recursive step: Let x be a new element constructed in the recursive step of the definition. Assume k 1, k 2, …, k WebStructural Induction University of Hawaii! Proving something about a recursively defined object using an inductive proof whose structure mirrors the object’s definition. ! Basis step: Show that the result holds for all elements in the set specified in the basis step of the recursive definition !

Web1.In structural induction you can use both numeric and string datatype,while in ordinary only numeric is allowed. 2.In structural there is base case and constructor case,while in ordinary there is base case ,induction hypothesis and induction step.And in structural there can be many base cases. WebOct 29, 2024 · Strong induction is another form of mathematical induction, which is often employed when we cannot prove a result with (weak) mathematical induction. It is similar to weak induction in that there is a base step and an inductive step.
WebConclusion: By the principle of strong induction, it follows that is true for all n 2Z +. Remarks: Number of base cases: Since the induction step involves the cases n = k and n = k 1, we can carry out this step only for values k 2 (for k = 1, k 1 would be 0 and out of range). This in turn forces us to include the cases n = 1 and n = 2 in the ...
