CPLEX 11

CPLEX 11 30wasted computation time exploring uninteresting portions of the tree. When set at 0 (default), the mipordindoption instructs Cplex not to use priorities for branching. When set to 1, priority orders are utilized.Note: Priorities are assigned to discrete variables using the .prior suffix in the GAMS model. Lower .priorvalues mean higher priority. The .prioropt model suffix has to be used to signal GAMS to export thepriorities to the solver.(default = GAMS PriorOpt)0 Do not use priorities for branching1 Priority orders are utilizedmipordtype (integer)This option is used to select the type of generic priority order to generate when no priority order is present.(default = 0)0 None1 decreasing cost magnitude2 increasing bound range3 increasing cost per coefficient countmipsearch (integer)Sets the search strategy for a mixed integer program. By default, Cplex chooses whether to apply dynamicsearch or conventional branch and cut based on characteristics of the model.(default = 0)0 Automatic1 Apply traditional branch and cut strategy2 Apply dynamic searchmipstart (integer)This option controls the use of advanced starting values for mixed integer programs. A setting of 1 indicatesthat the values should be checked to see if they provide an integer feasible solution before startingoptimization.(default = 0)0 do not use the values1 use the valuesmiqcpstrat (integer)This option controls how MIQCPs are solved. For some models, the setting 2 may be more effective than1. You may need to experiment with this parameter to determine the best setting for your model.(default = 0)0 Automatic1 QCP relaxation. Cplex will solve a QCP relaxation of the model at each node.2 LP relaxation. Cplex will solve a LP relaxation of the model at each node.mircuts (integer)Determines whether or not to generate mixed integer rounding (MIR) cuts during optimization. At thedefault of 0, generation is continued only if it seems to be helping.(default = 0)-1 Do not generate MIR cuts0 Determined automatically
