    99Using CPLEX 11.2 and PH - command-line:
    1010
    11 No fixing of continuous variables at the moment, as the resulting MIP is solvable.
    12 No slamming at the moment, although it perhaps should be pursued for acceleration.
     11No fixing of continuous variables at the moment, as the resulting EF MIP is solvable.
     12Slamming after iteration 100, but not really - we haven't defined variable slam priorities. Cycle breaking when length exceeds 30.

    18 1ef10: Converges in 14 iterations by fixing all 30 first-stage discrete variables. After solving remaining EF, objective=157242.24 (not as good as the others)
    19 2ef10: Converges in 8 iterations by fixing all 30 first-stage discrete variables. After solving remaining EF, objective=149743.78.
    20 3ef10: Quickly (< 10 iterations) fixes 26 of the 30 first-stage discrete variables, but then stalls. Some strong evidence of cycling, but it isn't real.
    21        After 26 iterations, it fixes all 30 first-stage discrete variables. TBD: Need to re-run for objective value.
    22 4ef10: Converges in 12 iterations by fixing all 30 first-stage discrete variables. After solving remaining EF, objective=162803.48
    23 5ef10: Converges in 7 iterations by fixing all 30 first-stage discrete variables. After solving remaining EF, objective=154772.42
     181ef10: Converges in 17 iterations. Post-EF objective=155475
     192ef10: Converges in 8 iterations.  Post-EF objective=149743.78
     203ef10: Converges in 26 iterations. Post-EF objective=151536.34
     214ef10: Converges in 12 iterations. Post-EF objective=162803.48
     225ef10: Converges in 15 iterations. Post-EF objective=153279.42

    2524Fix lag = 10 (with wwph-fixlag10.cfg).

    29283ef10: Converges in 32 iterations. After solving remaining EF, objective=149973.9
    30 4ef10:
     294ef10: Converges in 85 iterations. After solving remaining EF, objective=161147.9 - exhibits a lot of cycle-breaking.
    31305ef10: Converges in 51 iterations. After solving remaining EF, objective=153279.42
    3231
    3332Fix lag = 20 (with wwph-fixlag20.cfg).

     374ef10: ***FAILS TO CONVERGE - SLAMMING PRIORITIES ARE REQUIRED.
