I sometimes have professors who use their own names for things. For example in lecture one kept referring to the "perfect marriage algorithm" but after talking with him I'm fairly certain he was referring to the Stable marriage problem. This is a challenge for me as I prefer to learn a little about a topic before going to a lecture, or read up on points discussed in the lecture after it. Are there any suggestions on how to approach this? The prof from the example above told us not to use Google to learn material for the class. With that said, he's a very reasonable and intelligent man, but I've been in other classes where profs have used nonstandard terminology (such as in math saying solve a problem by symmetry) and it would be difficult to talk to them.
I don't want to offend them by suggesting the name their using is wrong, but it makes studying from other resources hard and I don't think it's practical to try to learn everything just from lecture.
