Run your test suite, look at the code coverage report, find out which bits of your code doesn't get exercised by the test suite, become aware that changes in those bits of your code probably won't trigger any failing tests if they

There are a few ways to ask the TSP question. One question is "give me the shortest route geometry", this problem is NP-hard and can't be verified easily, this is what you're thinking of. However, the decision version

We do too. The to-fix tool that we use tends to focus on things we can identify algorithmically, like broken links, isolated lines, mis-spellings, etc. We encourage all our staff to get out and map locally, and some have been highly invol
