Which asymptotic notation represents the lower bound of an algorithm’s growth rate?

Options

  • A. Big-O
  • B. Big-Ω
  • C. Big-Θ
  • D. More than one of the above
  • E. None of the above

Correct Answer (Detailed Explanation is Below)

B. Big-Ω

Detailed Explanation

Big-Ω (Omega) notation represents an asymptotic lower bound. It indicates that a function grows at least as fast as the specified bound, up to a constant factor, for sufficiently large input sizes. In algorithm analysis, Ω can describe a lower bound on running time or another resource. Remember the common distinction: O = upper bound, Ω = lower bound, Θ = tight bound.
