cplexnode properties

The CPLEX Optimization node provides the ability to use complex mathematical (CPLEX) based optimization via an Optimization Programming Language (OPL) model file. This functionality is available in the IBM® Analytical Decision Management product, but now you can also use the CPLEX node in SPSS® Modeler without requiring IBM Analytical Decision Management.

For more information about CPLEX optimization and OPL, see the IBM Analytical Decision Management documentation.

Table 1. cplexnode properties
`cplexnode` properties	Data type	Property description
`opl_model_text`	string	The OPL (Optimization Programming Language) script program that will be executed by the CPLEX Optimization node and then generate the optimization result.
`opl_tuple_set_name`	string	The tuple set name in the OPL model that corresponds to the incoming data.
`opl_data_text`	string	The definition of some variables or data used for OPL.
`output_value_mode`	string	Possible values are `raw` or `dvar`. If `dvar` is specified, on the Output tab the user must specify the object function variable name in OPL for the output. If `raw` is specified, the objective function will be output directly, regardless of name.
`objective_function_value_fieldname`	string	The field name to use in the output. Default is `_OBJECTIVE`.
