Some related terms:

  • cut and try - "marked by trial and error; cut–and–try methods, cut–and–try testing. First Known Use 1903."
  • hill climbing - "...starts with an arbitrary solution to a problem, then attempts to find a better solution by incrementally changing [elements] of the solution. If the change produces a better solution, an incremental change is made to the new solution..." Note, gradient methods are related to hill climbing.
  • kaizen, a continual1 improvement process, via a Plan - Do - Check - Act cycle, somewhat like using a series of small testing-and-correcting steps.

Note 1: wikipedia indicates continual is preferred to continuous here.
