WebDec 22, 2024 · A succinct encoding of Binary Tree takes close to minimum possible space. The number of structurally different binary trees on n nodes is n’th Catalan number. For large n, this is about 4 n; thus we need at least about log 2 4 n = 2n bits to encode it. A succinct binary tree therefore would occupy 2n+o (n) bits. WebExperiments with synthetic data sets.
