◇Common Pitfalls
Confusing space complexity with auxiliary space — space complexity includes input size, auxiliary space does not Treating amortized cost as the same as average-case cost — amortized analysis guarantees a worst-case bound over a sequence of operations, not a probabilistic expectation Forgetting that lower-bound proofs apply to a problem, not a specific algorithm — an individual algorithm can still be suboptimal Ignoring probabilistic analysis assumptions — results only hold when the assumed input distribution is realistic
◇Summary
TL;DR — Advanced topics extend basic algorithm analysis: space complexity tracks memory usage, amortized analysis averages cost over operation sequences, probabilistic analysis uses expected values over input distributions, and lower bounds prove minimum resource requirements for a problem.
