"Bad end of central directory record" Now, let's say I miraculously am able to install Symphony on my computer, great.. What steps do I need to take to install the Rsymphony library? Lastly, how do I figure this stuff out on my own, mainly, the installing the R library? (For example, in a google search , I see rsymphony used to be in the rPortfolio package.. How do I figure that out on my own? ) In advance, thank you to anyone kind enuff to help me along. -- Vie...

Hi list, Please tell me why sometimes RSymphony.dll crashes on Windows 7 (may be on other Windows too). I saw that it depends on input data. For example this code bring to crash: library('Rsymphony') mat = c(0, 1, -100.37967, 0, 0, 1, 0, 0, -200, 0, 0, 1, -0.4, 0, 0, 1, 0, 0, -0.4, 0, 0.5, 0, 0, 0, 0, 0, -1, 0, 0, 0) mat = matrix(mat...

Hi list, I have two question relating to the Rsymphony package: a) is there a way to use 'warm starts' ? i.e. if i successively call Rsymphony_solve_LP() with only one constraints change, does it perform the optimization from the simplex-origin or does it uses the previously found solution [i.e. as is common usage, see for instance lpsolveAPI...

I'll appreciate the help on the following problem: I solved many Nonlinear programming problems with nonlinear constraints....Rdonlp is working well but i am unable to get INTEGER data with nonlinear constraints in Rdonlp. Is it possible to get Integer Values of parameters in any package of R with nonlinear constraints. Rahul [[alternative HTML version deleted]]

Good Evening Does anyone in the R-help list have experience writing an R wrapper that interfaces with the commercial packages LINGO and/or LINDO.api from R? I have a set of nonlinear/mixed integer problems that solve nicely with LINGO but I would like to use R to set the problems up and analyze/plot the solutions dynamaically. I have searched the archives and have not found any R packages that

Hello All, Could anybody point me out any port of "Global Optimization Test Problems" OR "Constraint Satisfaction Test Problems" part of Coconut[%] benchmark or other such similar benchmarks for R.

Dear everyone, I don't know much about Integer Programming but am afraid I am facing a problem that can only be solved via Integer Programming. I was wondering if those of you who have experience with it could recommend an R package. I found the following R packages: Rglpk glpk lpSolve lpSolveAPI Are there any others? Are some of them easier to use than others for a beginner? Any advice

Dear all, I would like to solve a problem similar to a multiple knapsack problem and am looking for a function in R that can help me. Specifically, my situation is as follows: I have a list of n items which I would like to allocate to m groups with fixed size. Each item has a certain profit value and this profit depends on the type of group the item is in. My problem is to allocate the items

Hi, I have what I think is some kind of linear programming question. Basically, what I want to figure out is if I have a vector of numbers, > x <- rnorm(10) > x [1] -0.44305959 -0.26707077 0.07121266 0.44123714 -1.10323616 -0.19712807 0.20679494 -0.98629992 0.97191659 -0.77561593 > mean(x) [1] -0.2081249 Using each number only once, I want to find the set of five pairs where
