I have a somewhat large model
Coin0002I Problem BLANK has 157974 rows, 667812 columns and 10181088
elements
available for the nonce at http://www.sdcorp.net/deinst/KCMO.mps.bz2
In an effort to get it solving faster with little to no work on my part, I
tried the Dantzig-Wolfe decomposition using CoinStructuredModel (I fed the
mps to the decomp2 example.)
Kablooey.

(If this code is not ready, ignore me).
Thanks,
