What is the meaning of <- in AI?

Question

I've seen in a lot of AI-related stuff the symbol <-. For example,

delta <- 0 

 x <- x + 1

etc.

I always assume its meaning is the same as =(assignment), but probably they have a meaning that's a bit different from the assignment, I assume?

Thanks

Answer 1

It is an assignment operator. It removes ambiguity that the "=" symbol adds because this"=" symbol is often overloaded to test equality.

It makes things easy to understand that the thing on the left is being assigned the thing on the right, rather than being matched, unified, or otherwise made equal to it.
