Solution found of 363864
Before mini branch and bound, 8393 integers at bound fixed and 0 continuous
Full problem 122 rows 8458 columns, reduced to 40 rows 60 columns
Mini branch and bound did not improve solution (0.23 seconds)
After 0.23 seconds - Feasibility pump exiting with objective of 3 - took 0.21 seconds
Integer solution of 363864 found by feasibility pump after 0 iterations and 0 nodes (0.23 seconds)
Full problem 122 rows 8458 columns, reduced to 0 rows 0 columns
1 added rows had average density of 630
At root node, 1 cuts changed objective from 338864 to 340160 in 2 passes
Cut generator 0 (Probing) - 0 row cuts (0 active), 0 column cuts  in 0.012 seconds - new frequency is 10
Cut generator 1 (Gomory) - 13 row cuts (1 active), 0 column cuts  in 0.020 seconds - new frequency is 1
