On the boundary in general, if the boundary isn't bounded by hyperplanes like in this case.

Also that's IF there is an extremum it has to be on the boundary. You need compactness to omit this part IIRC.

I guess I knew this, I never thought about what derivatives of quotients of multivariable linar functions would look like.

I guess all the S variable are integers each so all of this is moot since there's only a finite number of possibilities.
(Except for w) w is bounded above by 9

And we're on a closed, bounded subset of R^n so bolzano-weierstrass tells me what I need to know here...

Is this something to do with CIV?

[Thorwaywhobia]

Probably.

Not that I care much though

[Xfxhbcxp]

The unfortunate thing for MRT is that none of that work is actually applicable to CIV, if that is indeed what MRT is using it for.

[plantBanceper]

I'm suprised MRT didn't know about the function minimisation anway. And we all know you like to show off your superiority KH

No real cygwin or djgpp experience.

But nauty seems to compile and work properly under a *nix environment without any problem.

Did you manage to unzip/untar the file yet?

Once you've done that, open a terminal in your emulator. cd to the nauty22 directory (or whatever version you have). type in "./configure" and hit enter. wait. shouldn't have any errors (i'm assuming your emulator comes with a functioning version of gcc). then type in "make all" and hit enter. wait.

now you should be able to run the included utilities. See I'm really new to this.
I played around in the emulator with a UNIX tutorial.
I was able to cd around a bit and create folders etc...
But I couldn't understand how my "root" or "home" was related to my actual hard drive.
Meaning I couldn't find my nauty directory from the emulator.
Maybe I needed to edit what my root was before running the emulator?

EDIT:
Anyway, for now, I'll try to see if I can avoid the whole UNIX business and try to compile it manually somehow.

[BrianGoldsmith]

Uhhh...no, I don't think so. I think that once you've compiled into an executable its ability to run is highly platform dependent. That's why I had to compile my fortran routine under a Windows compiler on a win-32 system to get a win-32 executable. This executable will not run under *nix, and vice versa.

But I'm not exactly an expert in this. Or even competent.

Btw I'm kind of interested..
Was it civ-related?
Can you explain where the question came from?

Also, how old are you?
Unless I have you confused with someone else, I thought you were over 20. It's a bit surprising to see people studying algebra at that age. By then, they have either gone through it or abandoned forever.
Although in any case, it's never too late for more math It IS in fact Civ related.

It has to do with chopping down forests.
