CPLEX 11

CPLEX 11 24.divflt (real)A diversity filter for a solution pool (see option solnpool) allows you generate solutions that are similar to(or different from) a set of reference values that you specify for a set of binary variables. In particular, youcan use a diversity filter to generate more solutions that are similar to an existing solution or to an existingpartial solution.A diversity filter drives the search for multiple solutions toward new solutions that satisfy a measure ofdiversity specified in the filter. This diversity measure applies only to binary variables. Potential newsolutions are compared to a reference set. This reference set is specified with this dot option. If no referenceset is specified, the difference measure will be computed relative to the other solutions in the pool. Thediversity measure is computed by summing the pair-wise absolute differences from solution and the referencevalues.(default = 0)dpriind (integer)Pricing strategy for dual simplex method. Consider using dual steepest-edge pricing. Dual steepest-edge isparticularly efficient and does not carry as much computational burden as the primal steepest-edge pricing.(default = 0)0 Determined automatically1 Standard dual pricing2 Steepest-edge pricing3 Steepest-edge pricing in slack space4 Steepest-edge pricing, unit initial norms5 Devex pricingeachcutlim (integer)This parameter allows you to set a uniform limit on the number of cuts of each type that Cplex generates.By default, the limit is a large integer; that is, there is no effective limit by default.Tighter limits on the number of cuts of each type may benefit certain models. For example, a limit on eachtype of cut will prevent any one type of cut from being created in such large number that the limit on thetotal number of all types of cuts is reached before other types of cuts have an opportunity to be created. Asetting of 0 means no cuts.This parameter does not influence the number of Gomory cuts. For means to control the number of Gomorycuts, see also the fractional cut parameters: fraccand, fraccuts, and fracpass.(default = 2100000000)epagap (real)Absolute tolerance on the gap between the best integer objective and the objective of the best node remaining.When the value falls below the value of the epagap setting, the optimization is stopped. This optionoverrides GAMS OptCA which provides its initial value.(default = GAMS OptCA)epgap (real)Relative tolerance on the gap between the best integer objective and the objective of the best node remaining.When the value falls below the value of the epgap setting, the mixed integer optimization is stopped. Notethe difference in the Cplex definition of the relative tolerance with the GAMS definition. This optionoverrides GAMS OptCR which provides its initial value.Range: [0,1](default = GAMS OptCR)
