WebLet us consider the fixed word of weight W and find the probability of there being a code in the LG-LDPC code ensemble such that this word is a codeword for this code. For this purpose, let us consider the first layer of the parity-check matrix of some LG-LDPC code from the ensemble composed of the parity-check matrices of the single parity check code.

WebDec 19, 2011 · The optimal solution for searching a simple sorted array is a Binary Search, which has time complexity O (log₂ (N)). The worst case happens when the searched-for element is not in the array, and takes exactly ⌊log₂ (N) + … WebThe best case for binary search is we find the target on the very first guess. That takes a constant amount of time. So, in the best case binary search is Ω(1), O(1), which also means it is Θ(1). On the other hand, in the worst case, where we don't find the target, binary search is Ω(log(n)), O(log(n)), which also means it is Θ(log(n)).
