Paper: A Model for Hierarchical Memory

Asymptotic complexity of algorithms (the “big-O” notation) is a staple of computer science and engineering. We usually focus on asymptotic worst-case time complexity. For example, we know that quicksort can take up to n2 steps to sort a sequence of … Continue reading
