Full_Name: wfeng Version: 2.7 OS: windows xp Submission from: (NULL) (208.62.252.2) for solveLP(linprog), the program is specified as Minimizes c'x, subject to A x >= b and x >= 0. However, what I found is the actual constraints that works with the function are A x <= b and x >= 0.

Hi everyone, i?m a new user of R and i?m trying to translate an linear optimization problem from Matlab into r. The matlab code is as follow: options = optimset('Diagnostics','on'); [x fval exitflag] = linprog(f,A,b,Aeq,beq,lb,ub,[],options); exitflag fval x=round(x); Where: f = Linear objective function vector (vector of 45,rows) A = Matrix for linear inequality

Dear all is there any linear programming routine available for R? if not, can you suggest any alternatives? not need to be very powerful, I get only a samll problem to resolve. many thanks yong

Hi, I am using R in one of my courses. I am trying to use R's linprog package to solve to formulate 2-class classification problem as Linear programming problem. For my formulation, I need to set to "cvec" to all 0s. I know the points are linearly separable so an optimal solution "x" does exist, which satisfies all the constraints. But given the constraints and setting

Greetings I'm a total newbie in R and I'm trying to make a comparisson of Excel and R in the fields of: - optimisation modeling (using solver) - decision trees - simulation modeling as described in Winston, Wayne L.: Practical Management Science. for optimisation modeling in Excel I would normaly use solver. In R however I can't seem to be able to find the solution. I've

Hi. I am aware of three different R packages for linear programming: glpk, linprog, lpSolve. From what I can tell, if there are N variables and M constraints, all these solvers require the full NxM constraint matrix. Some linear solvers I know of (not in R) have a sparse matrix input format. Are there any linear solvers in R that have a sparse matrix input format? (including the

I have a problem with new version (1.9.18p8) of SAMBA and username mapping.

Hello. I''m newbie with QoS. I read some articles and I have a question on You. If you have time to spare, it would be great if you reply. Here is my problem. I''m on wireless network(no earnig comunity). We got 2/2Mbit(soon 4/4) for 100 people(sharing link). Not long ago people start screaming that their games don''t work good(lagging). So I add to our qos class games

Good morning, I have two problems and I would like know if you can help me: 1- I have a printer "plotter-A0" installed in a windows98. There isn?t driver for this printer in the unix (solaris2.x). I would like to create a spool to this printer by the "admintool" but it left from the impression calls this printer automatically in the windows. It?s possible? 2- Every times

Hi! Can anyone let me know how can I get the stdDev of the random intercept from the output of glmmPQL? Thanks Salom?

Hi , Today I have the following sharing in "Samba version 2.2.12 for Solaris 2.9": [produto] write cache size = 384000 comment = AREA DE DADOS DE PRODUTO path = /usr/produto read only = No valid users = @produto where exists the users cs02929 pertaining to the group @produto. And everything

Hi , I need to do my user_windows "eng.processo" to acess my unix solaris 2.x as user_unix "cs02929". As like indicate, I create in "global" of file "smb.conf" the command: username map = /etc/smbusers and into the file /etc/smbuser, the command: cs02929 = "eng.processo". This it don?t work. Please, what do I do to this work? Do I forgot

Hi list, I want to find the total maximum resources I can spend given a set allocation proportion and some simple budget constraints. However, I get suboptimal results via lp and friends (i.e. lpSolve and simplex in the linprog and boot) . For example: library(lpSolve) proportions = c( 0.46, 0.28, 0.26) constraints = c( 352, 75, 171) lp(objective.in = proportions, const.mat =

Hi, I'm an R newbie and I've been struggling with a optimization problem for the past couple of days now. Here's the problem - I have a matrix of expected payouts from different stock option strategies. Each column in my matrix represents a different stock and each row represents the return to the strategy given a certain market move. So the rows are not a time series of percentage

Dear all, I am trying to find a solution satisfying the below equations in R. Set up the problem 9 X1+ X2 + X3 = 2 X1+ X2 + X3 = 1 which is subjected to 0 < X1 < X2 < X3 < 2. I have downloaded the packages \'linprog\' and \'lpSolve\' but can not see how to solve the question. Thank you for your help. With
