State
Target function
What you want done to the eigenvalues — 1/x, the sign function, e^{-ixt} — together with the domain it has to be right on. The domain is usually not the whole interval, and the piece it excludes is where the cost hides.
A state is an object you can be holding, named once so that two routes reaching the same thing are drawn as reaching the same thing. It says nothing about how you got here or where you can go next — that is entirely in the processes below.
This is a kind of
This state is not recorded as a kind of anything else. It stands on its own in the vocabulary.
Narrower kinds of this
No state in the vocabulary is recorded as a narrower kind of this one.
Records that are this object
Nothing in the catalogue has been joined to this state. That is a gap in the join rather than a claim that no such object exists; the shelf on /repository lists what is joined and what is not, with the reason.
Work that arrives here
No recorded process returns this. Either it is where a reader starts — a problem, a matrix, a machine — or it is an object this graph names and no route yet reaches.
Work that starts here
- Polynomial approximation
Given a target function, a domain and an error , return a polynomial of definite parity, bounded on , that is -close to the target on that domain, with an explicit degree.
