Bugs in programs remain a pernicious problem.  Research techniques in automated program improvement and repair are typically classified as either heuristic---searching over a set of syntactic changes, often drawn from an existing body of code---or semantic---leveraging symbolic analysis or synthesis to construct program-improving changes with respect to an inferred specification.  In this talk, I will outline our recent advances in techniques that lie squarely in the middle, drawing on the best of both worlds: We reason about desired program behavior semantically, and use that characterization to scalably identify and adapt pre-existing code to fix bugs automatically.  I will particularly emphasize the potential these approaches have to construct high quality patches, tackling a key outstanding challenge in the state-of-the-art in automated patching.
