问题 module MapHelpers (Ord : Map.OrderedType) = struct include Map.Make (Ord) let add_all a b = fold add a b end works but the seemingly equivalent module MapHelpers (Ord : Map.OrderedType) = struct include Map.Make (Ord) let add_all = fold add end fails to compile with File "Foo.ml", line 2, characters 18-104: Error: The type of this module, functor (Ord : Map.OrderedType) -> sig ... val add_all : '_a t -> '_a t -> '_a t end, contains type variables that cannot be generalized Command exited with

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 they use. If a target graph A has n nodes and m edges, then a chemist would accept subgraph matches in which a query graph B had n nodes and m-1 edges. The only requirement would be that every edge in B should be present in A. For example, a linear chain of 6

Why do monomorphic and polymorphic matter in JavaScript?

问题 I've been reading some articles on change detection, and all of them say that monomorphic functions are much faster than polymorphic. For example, here is a quote: (..)The reason for that is, that it has to be written in a dynamic way, so it can check every component no matter what its model structure looks like. VMs don’t like this sort of dynamic code, because they can’t optimize it. It’s considered polymorphic as the shape of the objects isn’t always the same. Angular creates change
