Error Message Examples

The lhs expression specified in NlpDefine returned a non-numeric value when evaluated
during the optimization.

Cause

You have passed an unrecognized parameter to the Parameter parameter to an optimization function (E.g. LpDefine, QpDefine or NlpDefine).

You can use the SolverInfo function to display all the Parameter that can be tweaked for an engine and also the valid ranges for the parameters. The following code displays all the settings and the range for the Linear and Quadratic engines.
Solverinfo(item: ['Settingnames', 'Minsetting', 'Maxsetting'], engine: 'LP/Quadratic')]

Remedies

Correct the parameter passed to the optimizer function to a valid parameter.
