r1736 r1746 9 9 Using CPLEX 11.2 and PH  commandline: 10 10 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.11 No fixing of continuous variables at the moment, as the resulting EF MIP is solvable. 12 Slamming after iteration 100, but not really  we haven't defined variable slam priorities. Cycle breaking when length exceeds 30. 13 13 14 ../../../scripts/runph modeldirectory=models instancedirectory=XXXX verbose maxiterations= 200 rhocfgfile=config/rhosetter1.0.cfg enablewwextensions wwextensioncfgfile=config/XXX.cfg solveef14 ../../../scripts/runph modeldirectory=models instancedirectory=XXXX verbose maxiterations=100 rhocfgfile=config/rhosetter1.0.cfg enablewwextensions wwextensioncfgfile=config/XXX.cfg solveef 15 15 16 16 Immediately fixing results (with wwphimmediatefixing.cfg). 17 17 18 1ef10: Converges in 14 iterations by fixing all 30 firststage 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 firststage discrete variables. After solving remaining EF, objective=149743.78. 20 3ef10: Quickly (< 10 iterations) fixes 26 of the 30 firststage discrete variables, but then stalls. Some strong evidence of cycling, but it isn't real. 21 After 26 iterations, it fixes all 30 firststage discrete variables. TBD: Need to rerun for objective value. 22 4ef10: Converges in 12 iterations by fixing all 30 firststage discrete variables.
