What's the Difference Between Subgraph Isomorphism and Subgraph Monomorphism?

In one of the projects I've worked on, the subject of isomorphism versus monomorphism came up. A little background: I'm no expert on graph theory and have no formal training in it. But this topic is very important in chemistry, where chemists expect a particular kind of subgraph matching to take place in the structure search systems the...

Why does F# function return a signature of "val FunctionName: int -> int"?

I was following some examples on F# Wikibook on High Order Functions. Second code snippet under title, Composition Function has following code snippet. #light open System let compose f g x = f (g x) let xSquared x = x*x let negXPlusFive x = -x/2.0 + 5.0 let fog = compose xSquared negXPlusFive // ...
