SolverInfo

The SolverInfo function provides information about a specific optimizer engine, or about a previously-defined LP, QP or NLP. Its declaration is:

SolverInfo( lp : optional LP_TYPE ; item : atomic text ; engine : optional atomic text ; 
            ref : optional boolean = False )

Where:

lp : A problem instance previously defined by LpDefine, QpDefine or NlpDefine, or returned by FindIIS.
item : A description of the desired item(s). See below.
engine: The name of a Solver engine.
ref : A flag indicating whether a reference to the result should be returned.

The Lp and Engine parameters cannot both be specified in the same call.

Obtaining Information about a Problem Instance

You can obtain information about a previously-defined optimization problem using the two-parameter form of SolverInfo:

 SolverInfo( lp, item )

For example, to get the variable lower bounds use:

 SolverInfo( lp, "lb" )

Possible values for the Item are
