Formula & Methodology
The formula to calculate the lower complexity of an algorithm with probability is:
C(n, p) = ∑ (nCk * p^k * (1-p)^(n-k)) * C(k)
Where:
- nCk is the combination of n and k
- p is the probability of each input being selected
- C(k) is the complexity of the algorithm for k inputs
