@OleksandrR. I presume your attempt has been using NelderMeadMinimizeDumpCompiledNelderMead rather than NelderMeadMinimize? I haven't tried the latter.
Mhm, I'm sorry I can't help :o Never heard of such a problem. I guess it just takes the lastest version of mathematica.. Unix for the win is all I have to say :D
@Öskå MMA9 and MMA10 should be entirely separate applications with their own directories etc. It's more like Windows Media Player opening when VLC should open, and since that doesn't happen it could be a problem that is caused by the Mathematica installer which is on topic here.
Although Superuser.SE might know what this is about as well.
@BeingHuman People are reluctant to help you because you have a long history of posting a question, linking to data, getting help and then removing the details from the question and the data. This makes the question useless for others and the answerers feel that their efforts are wasted.
@BeingHuman Yes, it is a serious allegation — something for which I've contacted you before and something I stand by. Here's the most recent one:
Could you put at least a sample of your data here so the answer below does not become completely meaningless? Otherwise this has all been a waste of effort in that it's useless for anybody but you. — aclJul 14 at 22:54
In any case, don't take it as criticism... you're not being punished or anything. Issues like this are discussed in here often and no one likes users that do that. I just wanted to let you know how people might feel.
I think they are interesting and we only have a few users here that are qualified enough to answer those questions. Your questions also require some effort to answer (which is good) and I only want that effort to be useful for others as well.
@rm-rf except error question, I have updated the data link, so now you have all the data. for error question, I dont remember the file, I was trying my self, and got those errors, later on, I guess deleted the notebook. Any way, the conclusion was to understand polygons and points, which is well explained in the answer.
Today we are proud to announce the release of Wolfram SystemModeler 4. For SystemModeler 4, we have expanded the supported model libraries to cover many new areas. We’ve also improved workflows for everything from learning the software to developing models to analyzing and deploying them. People have been using SystemModeler in an astonishing variety of [...]
@hwlau OK, one of the packages I mention does try to optimize expressions. Don't remember which one and don't remember how well. But what they do is collect duplicate subexpressions, mostly, not more C-specific stuff if there is any
@hwlau the package Optimize.m does this, from what I remember (the one I linked to above). Also something in mma does it, but I forget where precisely it is.
also look at second answer here (also first answer but the second seems ready-made)
@hwlau I'm familiar with how it works. I find symbolic manipulation (with mathematica or anything else) pretty much useless for real work. I use it for numerics
(I mean, for my real work; obviously others find it useful for theirs)
