Re: [Help-glpk] concave gain networks and non-global optima

[Robbie Morrison]

Hello Andrew, Axel, and Bob

Many thanks for the replies.

I found the following paper discussing, among other
things, various ways of specifying piecewise linear
costs (which look similar to the stepwise linear gains
I mentioned):

  Croxton, Keely L, Gendon, Bernard, and Magnanti,
      Thomas L.  2002.  A comparison of mixed-integer
      programming models for non-convex piecewise
      linear cost minimization problems.  Management
      Science, v49, pp1268-1273.

I obtained their working paper, released a year
earlier, with the same title (so I guess the content is
very similar):
