I am past chair of the INFORMS Computing Society, which has a lot of interesting members working on optimization, computer science and artificial intelligence.

Here's some information about research on network design and interdiction.

There is a typo in the "Sizes" paper: The paper "Optimal Selection of Subsets of Sizes for Production," with S. Jorjani and C. Scott International Journal of Production Research, 37 (1999), 3697-3710 has a typographical error in constraint (7): the summation is for j greater than or equal to i, but it should be for j less than or equal to i (you cannot cut something and make it bigger). This error was repeated (via cut and paste) in the appendix of the paper "A Class of Stochastic Programs with Decision Dependent Random Elements," with T.W. Jonsbraaten and R. J.-B. Wets, Annals of Operations Research 82 (1998) 83-106 where the "sizes" problem was used as an example.

The smps file sizes.cor did not have this error. However, sizes.cor does have one error:

Y06JJ01 P06JJ01 -1.0 P05JJ02 -1.0

should be

Y06JJ01 P06JJ01 -1.0 P06JJ02 -1.0

This error of course also appears in deterministic equivalents generated from the file sizes.cor, such as sizes3.mps, etc. Of course none of the algorithmic conclusions are affected by this, but I regret the error nonetheless because I know it create confusion if you try to duplicate the results.
