Dear R Community, I am trying to optimize a water quality model that I am using. Based on conversations with others more familiar with what I am doing I plan to implement DEOptim to do this. The water quality model is interfaced through a GUI. I have the input file necessary to alter parameters and run the model as a text file. To do the optimization I have figured out the general procedure

Dear All, We are happy to announce the release of the new version of DEoptim (version 2.0-0) which is now available from CRAN. The DEoptim package [3] performs Differential Evolution (DE) minimization, a genetic algorithm-based optimization technique [2,3]. This allows robust minimization over a continuous (bounded or not) domain. The new DEoptim function calls a C implementation of the DE

(the same mail was sent to the author) When I called the function DEoptim with control=list(strategy=1) or control=list(strategy=2) I got the error: Error in mui[rtd + 1, i] : incorrect number of dimensions Analysis of the source code of the DEoptim reveals the following fragment if (con$strategy > 5) st <- con$strategy - 5 ## binomial crossover else { st <-

Function DEoptim in package DEoptim for differential evolution defines an optional parameter fnMap: fnMap "an optional function that will be run after each population is created, but before the population is passed to the objective function. This allows the user to impose integer/cardinality constriants." Unfortunately, there is no further documentation decribing the kind of

Dear R Community, I am trying to run a command line in R that will open an external program, have it import a specific input file, run the program, then close the program. The command line that I got from the developer of the model to do this looks like what you see below: c:\programx.exe -import 'inputx.inp' -run -quit I have been trying to use shell() or shell.exec() to run this in

Dear R users, During the the running of DEoptim function which belongs to "DEoptim" package it automatically gives the output like the following: Iteration: 1 bestvalit: 181.379847 bestmemit: 0.226499 1.395852 Iteration: 2 bestvalit: 14.062649 bestmemit: 2.290357 5.597838 Iteration: 3 bestvalit: 14.062649 bestmemit: 2.290357 5.597838 Iteration: 4 bestvalit: 14.062649

Hello, I was wondering if someone could tell me how I can make text dependent on a variable in a R function I have created. The function will create plots, thus I would like each plot to have a unique title based on the inputted variable as well as a unique file name when saved using the savePlot function. Thanks! Rachel

Not sure if this is a bug yet, so I wanted to ask around to see if anyone else was having this issue. I have pollmailboxes=yes set in voicemail.conf but externnotify is not called. I know it isn't the externnotify script because if the changes are done in asterisk then it is called properly, if the changes are done via our webserver then it is not. Also, we use odbc voicemail storage. Thanks

Dear R community, I am looking for the package "Rsafd". It is not listed on the CRAN directory. I am wondering anyone has idea with this package. Thans a lot!

Hi, I want to use the neural network package AMORE and I don't find in the documentation the weight decay option. Could someone tell if it is possible to add a regularization parameter (also known as a weight decay) to the training method. Is it possible to alter the gradient descent rule for that? Thanks, Ron

Hi, I need to perform some transformation after code was lowered. I think I need to do this in llc and use a MachinePass. However, it is unclear how. I am able to change the register allocator: llc -f -load XXX.so -regalloc=xxx foo.bc but I don't know how to just insert a different pass and pass new command options to llc. I found plenty of documentation about 'opt', but little

Hi, I have a situation where the files I'm backing up are written to every fifteen minutes or so. There's a good possibility that rsync will try to copy a file while it is being written into, and I'm wondering if there's any risk that the _source_ file will be damaged? I've seen similar posts about the target file, but my concern is the source. Additionally, would the writing

Hi, I am trying to create a spatial weight matrix based on the neighboring relationship among Europan countries. Can I use the map function in R to generate a European map and then use this map to build the w weight matrix? So far, I cannot create a map for Finland using the map function. Also, I am not very sure about the steps in importing external map data and use that information to

Hi R-Core, i am using nnet and DEoptim, Xcc=matrix(rnorm(100,0.5,0.08),50,2) Ycr=matrix(rnorm(50,0.2,0.05),50,1) pred_regm1 <- function(A) { A1=A[1] A2=A[2] A3=A[3] regm1 <- nnet(Xcc,Ycr,entropy=T,size=A1,decay=A2,maxit=2000,trace=F,Hess=T,rang=A3,skip=T) dif=sum((predict(regm1,Xcc)-Ycr)^2) return(dif) } somar=DEoptim(pred_regm1,c(1,0.00001,0.01), c(25,0.999,0.95),

can anyone know where i can find information on compile hmisc on windows, especially 64 windows? thanks, _________________________________________________________________ The New Busy is not the too busy.

I have defined a function with several arguments and have it stored in the .RData file. The 'function head' is defined as follows EstimALIConc <-function(sdname,SZ,W,farea,watri,biomodel,start.part=1,nparts=20,method=c("optim","DEoptim")) { [ blah-blah-blah ] (function body doesn't matter) } Then I call Rscript: e:> rscript --restore -e

Hi there, I am trying to fit the following model with a sum of exponentials - y ~ Ae^(-md) + B e^(-nd) + c the model has 5 parameters A, b, m, n, c I am using nls to fit the data and I am using DEoptim package to pick the most optimal start values - fm4 <- function(x) x[1] + x[2]*exp(x[3] * -dist) + x[4]*exp(x[5] * -dist) fm5 <- function(x) sum((wcorr-fm4(x))^2) fm6 <- DEoptim(fm5,

Dear all, I'm pleased to announce the release of an R implementation of the Self-Organising Migrating Algorithm (SOMA), a general-purpose, stochastic optimisation algorithm. The approach is similar to that of genetic algorithms, although it is based on the idea of a series of "migrations" by a fixed set of individuals, rather than the development of successive generations. It can be
