0. blp9-6.ine.out0-98 (ext file) was computed form blp9-6.ine and is only a partial output. The run using mplrs v7.1 took about 8 months using between 200 and 420 processors, in 98 checkpointed runs. 1. To convert blp9-6.ine.out0-98 (ext file) to p9-6.ext0-98 in full S_A+S_B basis: remove all lines except the ext ray matrix % blp2lp < blp9-6.ine.out0-98 > zfile % lmax 9 6 -2 < zfile > p9-6.ext0-98 This recomputes S from w and pretty prints Need to fill in m and set n=100 In this case we obtained: p9-6.ext0-98 *computed from blp9-6.ine.out0-98 V representation begin 333466 100 integer 2. To convert p9-6.ext0-98 to h9-6.ext0-98 % lmax 9 6 6 < p9-6.ext0-98 > h9-6.ext0-98 Then remove duplicates by % sort -u h9-6.ext0-98 > temp and reconstruct h9-6.ext0-98 from temp using an an editor 3. Since h9-6.ext0-98 was constructed from the S_B space only we need to add in the S_A extreme rays. This can be done by merging with h8-6.ext which was completely computed then removing duplicates again. We obtain h9-6.ext.part with 213,225 extreme rays.
