This dissertation is concerned with the question of formally verifying that the implementation of an algorithm is not only functionally correct (it always returns the right result), but also has the right asymptotic complexity (it reliably computes the result in the expected amount of time).In the algorithms literature, it is standard practice to characterize the performance of an algorithm by indicating its asymptotic time complexity, typically using Landau’s “big-O” notation. We first argue informally that asymptotic complexity bounds are equally useful as formal specifications,because they enable modular reasoning: a O bound abstracts over the concrete cost expression of a program, and therefore abstracts over the specifics of its implem...
