The bad news is I think these examples are lost to history.
The good news I have some better ones. Do you think the new wiki is a good

I am trying to use GLPK on R on MAC os.
Can you please give me an example of how to use the GLPK for
solving a linear program for a system at steady state, the R.H.S. is
zero.
If your model is LP or MIP, you can use glpsol, the stand-alone
glpk lp/mip solver which supports the modeling

Hi,
I #8217;m running an LP through the R version of GLPK

and comparing the results with what I get out of AMPL (using the cplex solver,
but that #8217;s probably not important).
While in AMPL I get a reasonable answer so the model

I have been working with glpk accessed from R. Originally I was
using the “glpk” R package in order to use the various API routines,
but eventually realized that this port is of glpk version 4.8 from
2006. To support my own work, I have updated the port to hook up
with version 4.43.
I
Hello Ken,
have a look at
ftp://cran.r-project.org/pub/R/contrib/main/Rglpk_0.3-5.tar.gz
The changelog says
UPDATED: Rglpk now includes GLPK version 4.42

Hi Xypron. I don't think Rglpk accesses the broad glpk API; it can simply read
problem description files and pass the specified problem to the glpk solver.
