The following default feature steps were used for model building:
Pre, Basic, KLB, CG
Number of presolved instances: 0
The cost for using the feature steps (adapted for presolving) is: 0
or on average: 0
The feature steps correspond to the following 50
/ 115
instance features:
nvarsOrig, nclausesOrig, nvars, nclauses, reducedVars,
reducedClauses, vars_clauses_ratio, POSNEG_RATIO_CLAUSE_mean, POSNEG_RATIO_CLAUSE_coeff_variation, POSNEG_RATIO_CLAUSE_min,

31
to 8
, resulting in a PAR10 score of 4281.406
for the reduced model. Analogously, the model that was generated based on 6
of the originally 113
features resulted in a PAR10 score of 4035.973
.
