similar to: Error using the Rdonlp2‏ Package

Previous versions have this question have partially bounced. I apologize if parts of this are showing up multiple times on the list. Another try ... There was at one time an R package called Rdonlp2 for solving constrained nonlinear programming problems. Both the objective function and the constraints could be nonlinear in the decision variables. The package is no longer in the CRAN list.

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

Hi R, A quick question.... How can I optimize the objective function constrained to quadratic constraints? Which function of R is useful for quadratic constraints? Many Thanks, Shubha This e-mail may contain confidential and/or privileged i...{{dropped:13}}

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

Hi Guys, Recently I wrote a package for dealing with Markov Switching Regressions in R and it is included in the Rmetrics project. https://r-forge.r-project.org/projects/rmetrics/ Everything works fine when I use it in computer. But, the package depends on the use of optimization functions from the package Rdonlp2, which is not available on CRAN. So, if I have Rdonlp2 in my laptop (or any

Dear all, this is my first message to this mailing list - please advise if it is not the right place for the subject I've been using R very intensively the last 3-4 years and one of the most tedious tasks is modification of lookup or conversion tables So far, I have not found functions that create the commands for creating objects (vectors, data frames) based on the objects themselves -

Dear Bo, Please keep the mailing list in cc. Your function only works properly with a data.frame in which all variables are characters. dput() will preserve the structure of the object and works with all R objects. Best regards, ir.

Hi I need advice regarding constraint optimization with large number of variables. I need to solve the following problem max f(x1,...,xn) x1,..xn x1=g1(x1,...,xn) . . xn=gn(x1,...,xn) I am using Rdonlp2 package which works well until 40 variables in my case. I need to solve this problem with over 300 variables. In this case Rdonlp2 is very very slowly. I know

Dear Sir, I installed successfully using the install.packages("Rdonlp2", repos=" http://R-Forge.R-project.org"). I tried on the example which is defined on the Rdonlp help file ,p <- c(-10,10)par.l <- c(0,0); par.u <- c(100,100)lin.u <- 1; lin.l <- 1A <- t(c(1,1))fn <- function(x){ x[1]^2+x[2]^2}ret <- donlp2(p, fn, par.lower=par.l, par.upper=par.u, A=A,

All, I have searched the previous help boards and discovered the problem with Rdonlp2 - Specifically, its non-availability. I thought that this was my solution, but perhaps there is a better way that you all could help me with. I imagine that this problem is trivial to people such as the experts on this mailing list. I am trying to solve this problem over and over again in a simulation:

Dear All, I couple of weeks ago, I’ve asked for a package recommendation for nonlinear optimization. In my problem I have a fairly complicated non-linear objective function subject to one non-linear equality constrain. I’ve been suggested to use the *Rdonlp2* package, but I did not get any results after running the program for 5 hrs. Is it normal to run this type of programs for hours? Also,

Hello R users, Can anyone recommend me any package that can be used to solve linear programming subject to nonlinear equality/inequality constraints. Rdonlp2 is now unavailable due to licensing issue. Thanks, Xiaoxi [[alternative HTML version deleted]]

Does anyone know how to do an Hausman test? I?ve estimate a modell (some alternatives) with clogit an wanted to test the IIA test (Independence of Irrelevant Alternatives) after estimating a multinomial logit model? Thank you

Hello Listers, does anyone know about virus scanners working on Unix hosts but scanning for all those bad vermin from the M$ world. Best solution (for me) would be a tight coupling with samba, monitoring the I/O as some PC scanners do. Any suggestions? TIA, -- Detlef ////

Dear R users, I have a problem. I would like to solve the following: I have pL = 1/(1+e^(-b0+b1)) pM = 1/(1+e^(-b0)) pH = 1/(1+e^(-b0-b1)) My target function is TF= mean(pL,pM,pH) which must equal 0.5% My non-linear constraint is nl.Const = 1-(pM/pH), which must equal 20%, and would like the values of both b0 and b1 where these conditions are met. I have searched widely for an answer,
