CS 5010: Module 07
Some problems are not easily solved using our usual observer templates. Others are solved only inefficiently by following those templates. We introduce two new kinds of generalization to help solve such problems. We introduce invariants as a way of recording the assumptions that a function makes about its environment.
Read Part VI from our textbook. We are doing things in a different order than the textbook. We are also doing this topic rather differently, so use the textbook as background rather than as a normative reference.
