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

"Item"	Valid For	Dimensionality	Type
"objcoef"	LP, QP	Vars	numeric
"Q"	QP	Vars, Vars2	numeric
"lhs"	LP, QP	Vars, Constraints	numeric
"rhs"	LP,QP,NLP	Constraints	numeric
"lb"	LP,QP,NLP	Vars	numeric
"sense"	LP,QP,NLP	Constraints	'>=','<=', or '='
"ub"	LP,QP,NLP	Vars	numeric
"ctype"	LP,QP,NLP	Vars	'C', 'I', or 'B'
"maximize"	LP,QP,NLP	atomic	True, False
"engine"	LP,QP,NLP	atomic	text
"setting"	LP,QP,NLP	local .Parameter	numeric
"type"	LP,QP,NLP	atomic	"LP","QP", "QCP" or "NLP"

Obtaining Information about a Solver Engine

The usage:

SolverInfo( engine: atomic text ; Item : atomic text )

returns information about a solver engine. The possible values for Item in this usage are:

Item	Dimensionality	Type	Description
"Setting"	Local .Parameter	numeric	Array of control parameters
"MaxSetting"	Local .Parameter	numeric	upper bounds for setting
"MinSetting"	Local .Parameter	numeric	lower bounds for setting
"Name"	atomic	text	The engine name
"DLL"	atomic	text	File path to solver engine's DLL
"TrialPeriod"	atomic	numeric	number of days until Frontline solver trial license expires
"MaxVars"	atomic	numeric	Maximum number of decision variables supported by engine
"MaxIntVars"	atomic	numeric	Maximum number of integer variables supported by engine
"MaxConstraints"	atomic	numeric	Maximum number of constraints supported by engine
"MaxVarBounds"	atomic	numeric	Maximum number of variable bounds supported by engine.
"Milliseconds"	atomic	numeric	Time spent in computation.
"Iterations"	atomic	numeric	# of iterations engine has performed
"Calls"	atomic	numeric	# of function evaluations that have occurred
"Jacobians"	atomic	numeric	# of jacobians evaluations that have occurred
"Hessians"	atomic	numeric	# of hessians evaluations that have occurred
