Error Message Examples

The value of the Setting parameter to LP_Definition is not a 1-D array (after array abstraction).
Since the optional 'Parameter' parameter is not specified, the value to the setting parameter 
needs to be a 1-D array where the index values contain the optimizer parameter name.

Cause

The Setting parameter passed to the function (LpDefine or QpDefine or NlpDefine) was not a 1-D array indexed by the Parameter it is setting, and no Parameter parameter is passed to the function either. The Setting parameter must either be indexed by Parameter or the Parameter parameter must be passed.

The Setting and Parameter parameters to the above functions can be used to set the search settings. (To get a list of Parameters that can be set for an engine, you can use the SolverInfo function.) These two parameters can be used in the following ways to set the search settings.

Specifying both the parameters:
LpDefine( ... , Parameter: [ 'MutationRate', 'SolutionAccuracy'] , Setting: [0.15, 1m]);

Specifying only the Setting parameter:

Index IndexOfParameters
Definition: ['MutationRate', 'SolutionAccuracy'];

Object SettingToLP
Definition: Table(IndexOfParameters)( 0.15, 1m );

Defining the optimization problem: LpDefine( ... , Setting: SettingToLp);


Please click here for documentation on setting the search parameter for functions LpDefine and NlpDefine.

Remedies

You can resolve this issue either by passing in the Parameter parameter to the optimization functions or by passing a 1-D array indexed by Parameter to the Setting parameter.
