Test data

Presents a data checking tool.

CPLEX provides a parameter to check the correctness of data used in problem creation and problem modification methods: the data consistency checking and modeling assistance (DataCheck or CPX_PARAM_DATACHECK). When this parameter is set, CPLEX will perform extra checks to confirm that array arguments contain valid values, such as indices within range, no duplicate entries, valid row sense indicators and valid numeric values. These checks can be very useful during development, but are probably too costly for deployed applications. The checks are similar to but not as extensive as those performed by the CPXcheck Data functions provided for the C API. When the parameter is not set (the default), only simple error checks are performed, for example, checking for the existence of the environment.
