Hi,

A paper that's very related to the CuttingTheBill paper is this
workshop (HotPower 09) paper by Ricardo Bianchini(Rutgers) et al.:
http://www.cs.rutgers.edu/~ricardob/papers/hotpower09.pdf

They are nearly concurrent, and this one cites the workshop paper that
preceeded CuttingTheBill. Here they present an optimization model (not
strictly an LP) for the problem, but there are many similarities.

Reading is optional...

Take care,
Rodrigo

Some comments on this that I will probably forget by tomorrow:

- They don't take into account bandwidth costs at all, either as a
strict upper bound or as a penalty function in their objective. One
could argue that their load capacity for each data center is a strict
upper bound on bandwidth, but it isn't complete (multiple links could
have different bandwidths coming in from different ISPs, etc)

- What is their annealing factor? Did they even tune this at all? Are
they really using the simulated annealing algorithm from 1983? (There
have been a few advances since then in the field of continuous
optimization...)

- How non-linear are the non-linear parts of their model? Can they be
approximated to a linear function? (If yes, the gains could outweigh a
simulated annealing approach)

- I like the separation of "Brown" vs. "Green" energy
