23 | Let $G=\tup{V,E}$ be a \termref[cd=binary-trees]{balanced binary tree} | ||
24 | of \termref[cd=graph-depth,name=vertex-depth]{depth}$n>i$, then the set | ||
25 | $\defeq{\livar{V}i}{\setst{\inset{v}{V}}{\gdepth{v} = i}}$ of | ||

30 | \item | ||
31 | \begin{sproof}[id=size-lemma-pf,proofend=,for=size-lemma]{via induction over the depth $i$.} | ||
32 | \begin{spfcases}{We have to consider two cases} | ||
33 | \begin{spfcase}{$i=0$} | ||
34 | \begin{spfstep}[display=flow] | ||
35 | then $\livar{V}i=\set{\livar{v}r}$, where $\livar{v}r$ is the root, so | ||
36 | $\eq{\card{\livar{V}0},\card{\set{\livar{v}r}},1,\power20}$. | ||
37 | \end{spfstep} | ||
38 | \end{spfcase} | ||
39 | \begin{spfcase}{$i>0$} | ||
40 | \begin{spfstep}[display=flow] | ||

42 | \begin{justification}[method=byIH](IH)\end{justification} | ||
43 | \end{spfstep} | ||
44 | \begin{spfstep} | ||
45 | By the \begin{justification}[method=byDef]definition of a binary | ||
46 | tree\end{justification}, each $\inset{v}{\livar{V}{i-1}}$ is a leaf or has | ||
47 | two children that are at depth $i$. | ||
48 | \end{spfstep} | ||
49 | \begin{spfstep} | ||
50 | As $G$ is \termref[cd=balanced-binary-trees,name=balanced-binary-tree]{balanced} and $\gdepth{G}=n>i$, $\livar{V}{i-1}$ cannot contain | ||
51 | leaves. | ||
52 | \end{spfstep} | ||
53 | \begin{spfstep}[type=conclusion] | ||
54 | Thus $\eq{\card{\livar{V}i},{\atimes[cdot]{2,\card{\livar{V}{i-1}}}},{\atimes[cdot]{2,\power2{i-1}}},\power2i}$. | ||

61 | A fully balanced tree of depth $d$ has $\power2{d+1}-1$ nodes. | ||
62 | \end{assertion} | ||
63 | \item | ||
64 | \begin{sproof}[for=fbbt,id=fbbt-pf]{} | ||

66 | Let $\defeq{G}{\tup{V,E}}$ be a fully balanced tree | ||
67 | \end{spfstep} | ||
68 | \begin{spfstep} | ||
69 | Then $\card{V}=\Sumfromto{i}1d{\power2i}= \power2{d+1}-1$. | ||

74 | \begin{note} | ||
75 | \begin{omtext}[type=conclusion,for=binary-tree] | ||
76 | This shows that balanced binary trees grow in breadth very quickly, a consequence of | ||
77 | this is that they are very shallow (and this compute very fast), which is the essence of | ||
78 | the next result. | ||
