@Mego My biggest problem with VB was when I tried to write a chess program during my first year, and I wanted to add a property to the PictureBox object to know whether or not a piece had been captured, so I ended up creating a new object called PictureBoxProperty that inherited PictureBox and just had a single extra property. Well, VB decided every few days to revert all of my PBP objects back to regular PictureBox objects and all of my code broke until I fixed it.

Can you use recursion in JavaScript? The following code is throwing a call stack exception f=n=>n==3?true:f(n++) calling f(1). Also, let me know if this is not the place to ask.

TuxCopter

You should be using ++n

Kritixi Lithos

Try f(++n) instead since when you call f(n++) the original value of n(1) is passed to f and then n is incremented

n++ evaluates to n and increment n

Anyone here an expert on functional programming?

I'm trying to learn it, but it is hard to switch from OOP.

Gabriel Benamy

@Hosch250 I never really learned what functional programming is

Hosch250

@GabrielBenamy That's kind of what I'm trying to find out.

I'm building a Checkers AI in F# as part of an Individual Studies class.

quartata

@Hosch250 What are your questions?

Hosch250

18:11

I'm trying to decide whether each piece should track its position or not.

Or should my Board track the piece's positions.

Each piece is immutable, BTW.

As is the board. Everything gets created new each time something changes.

Should I store the pieces in an 8x8 array, or in a list (only an option if the pieces track their own positions)?

Or do something else?

quartata

I think F# has sparse matrices of some form

Hosch250

Now I need to look those up.

quartata

Some form of matrix seems the most intuitive

I'm not sure if the pieces really need to store their positions. There's no logic specific to any one piece since they're all the same so most of your functions will probably be operating on the whole board or some submatrix of it

Hosch250

Yeah.

In OOP, I'd just use a 2d array and loops for iteration.

I know FP uses recursion instead.

I don't know if it uses the 2d array, though.

I'm looking up matrices now.

So, I'd store it as a sort of Dictionary<coord, piece>?

Looks like F# PowerPack has a sparse matrix somewhere.

@Dennis This keeps getting better and better. Pari/GP wants to install ModemManager, and mathjax.

@KritixiLithos It's not both of them. The Ó is part of the search, not it's own search command. In a search command it translates to \S, which is a non-whitespace character

is there a name for this operation over f: foo(f) = (a, b) -> map(a, x -> map(b, y -> f(x, y)))

Gabriel Benamy

what?

Conor O'Brien

e.g. x -> foo(*)(x, x) is a multiplication table using x. I thought this might be called "table"

@Dennis works for me, thanks!

Gabriel Benamy

@ConorO'Brien can you explain that better? I'm confused

@ConorO'Brien table, outer product

feersum

^ That's what the Mathematica builtins are called, anyway.

CMC: Given a letter input [a-z], output the English alphabet starting with that letter, wrapping z to a, and finishing with the prior letter. Example: input f output fghijklmnopqrstuvwxyzabcde code-golf

@TimmyD Where's the e?

feersum

In the ellipsis, of course.

MetaEd

Can't spell ellipsis without e.

@MartinEnder ahhh that's right.

If x and y are numeric lists, then x */ y  is their multiplication table. Thus:
   1 2 3 */ 4 5 6 7
 4  5  6  7
 8 10 12 14
12 15 18 21

TimmyD

@KritixiLithos It is actually in it.

@GabrielBenamy

MetaEd

@feersum In fact this means input f output f... is an accepted solution and that'll simplify the code considerably.

feersum

Why the f? ... should do.
