In my post at https://stat.ethz.ch/pipermail/r-help/2011-October/292019.html I
included an undefined term "ej". The problem code should be as follows. It
seems like a simple linear programming problem, but for some reason my code is
not finding the solution.
obj <- c(rep(0,3),1)
col1 <-c(1,0
Dear All,
RGLPK says that there is no feasible solution but I think there should be. In
a more general setup with more variables, where we know the feasible solution
analytically, it also says there is no feasible solution. I have tried
different values. except the 0s and 1s must stay as they
Dear All,
Thank you for the replies to my first thread here:

So far the best result is achieved via a penalised objective function. This
was suggested by someone on this list privately. I am still l
Dear All,
I would like to minimise a nonlinear function subject to linear inequality
constraints as part of an R program. I have been using the constrOptim
function. I have tried all of the methods that come with Optim, but nothing
finds the correct solution. If I use the correct solution as
