There have been several messages on R-devel mentioning the interior point optimization software Ipopt, https://projects.coin-op/Ipopt/. This C++ library is released under a license called the Common Public License. I have two questions that readers of R-devel may be able to answer. 1) Would creating an Ipopt interface for R be duplicating existing efforts? That is, has someone already done so

Dear all, I'm wondering if there are some ongoing projects for interior point methods in R (e.g. linking ipopt from Coin written in C++ to R) and for automatic differentiation in R (e.g. linking openAD available in C++ and Fortran) ? Many thanks, David [[alternative HTML version deleted]]

Hi. I need some advises on how to use R to find pi (i is the index) with the following objective function and constraint: max (sum i)[ f(ai, bi, pi) * g(ci, di, pi) * Di ] s.t. (sum i)[ f(ai, bi, pi) * Di * pi] / (sum i)[ f(ai, bi, pi) * Di ] <= constant f and g are diffentiable. So, I am thinking of optim with method = "BFGS"? But wonder how to include the

Dear list, The task view on optimization does not reference a package for non linear constrained optimization problems. Stefan Theussl told me to look at the Rsolnp package, but unfortunately it is not very clear what method is R ported. (The authors ported the matlab code of Yinyu Ye http://www.stanford.edu/~yyye/ <http://www.stanford.edu/%7Eyyye/>) Currently I'm looking for an

Hi, I'm trying to compile rsync 3.1.1pre2 on OS X with CFLAGS=-I/opt/local/include.

I am sending a patch that makes the debugging output of PXELINUX slightly more concise, without (intentionally) affecting its completeness at all. Additionally, I am proposing that the debugging output of PXELINUX -- specifically the messages that appear after the copyright statement, but before the menu is loaded -- only be shown in response to keyboard input (such as holding Shift or Alt, or

Dear R Users, I am looking for some guidance on setting up an optimisation in R with non-linear constraints. Here is my simple problem: - I have a function h(inputs) whose value I would like to maximise - the 'inputs' are subject to lower and upper bounds - however, I have some further constraints: I would like to constrain the values for two other separate function f(inputs) and

From: Matt Fleming <matt.fleming at intel.com> Since we can't use __intcall() for EFI, and since we can now have the ELF module code resolve all our symbols at runtime, we should delete as many references to __intcall() as possible and just access the symbols directly. The most interesting patch is the support for weak symbols. We need to be able to reference derivative-specific

Hi Peter, The main part of this pull request includes commits that try to replace as many __intcall() invocations as possible. Some remain, but not many (and eventually they'll be gone too). There's also a patch to make better use of ld's --as-needed option and various other bug fixes/cleanups. The following changes since commit ff7334a2ce536b7f4b1f6d6f93ff4e285a3bd45a: Only

Hi, We are using pxelinux at my company to test our product. And there are limitations that we have hit in the past w.r.t. the max length of a path, or the max length of a module name (in mboot.c / mboot.c32). We've used workarounds in the past, and reorganized the directory structure, but we face that problem again. Out of the 128 / FILENAME_MAX chars that can be used, 110 - 120 go to the

In my recent security email, I got the following errors: cantona.dnswatchdog.com login failures: Aug 20 02:37:19 cantona sshd[9444]: fatal: Write failed: Operation not permitted Aug 20 04:30:42 cantona sshd[16142]: fatal: Write failed: Operation not permitted Aug 20 21:21:51 cantona sshd[45716]: fatal: Write failed: Operation not permitted So three questions: What is it?

Background: I recently wrote to Peter Anvin regarding IPAPPEND functionality, and he suggested I take the issue to this mailing list. I see it has been touched upon several times, after reviewing the archives. Let me see if I can add to it with a good level of detail: When using PXE to network boot a linux client, PXE must first acquire the client's IP address, by dhcp request, then, the

From: Matt Fleming <matt.fleming at linux.intel.com> This is a series of patches that, * shrink the core by moving things into an ldlinux ELF module * begin wiring up some of the C versions of various functions The core now only contains essential code and loads the ldlinux module to do everything else, like providing a command line interface and loading kernels.
