lp_get(++ParamName, ?Value)

   Obtain the value of a global parameter.

Arguments
   ParamName           Atom or structure
   Value               Variable, integer, float or atom

Type
   library(eplex)

Description
    Eplex has a number of global (i.e. not specific to a
    particular problem) parameters. These can be queried using this 
    predicate.

    has_indicator_constraints
	Returns 'yes' if the solver supports =&ge;/2 indicator constraints,
	else 'no'.
    has_miqp
	Returns 'yes' if the solver supports mixed integer problems
	with quadratic objectives, else 'no'.
    has_qp
	Returns 'yes' if the solver supports quadratic objectives,
	else 'no'.
    optimizer
	Returns the name of the external solver, currently
	'cplex', 'xpress', 'osi' or 'gurobi'.
    optimizer_version
	Returns an integer derived from the version of the
	external solver (for osi, the version is the actual solvers
        used, including any significant third-party packages such as 
        sparse matrix ordering packages required by the barrier solver)
    presolve
	Returns the default presolve setting for solver setup, i.e. the
        presolve setting that a solver state would be given if it was not
        directly specified during setup. A value of 0 disables presolving.
	A value of 1 either enables presolving (for external solvers that
	have only global parameters), or uses the default optimizer_param
	settings (for external solvers with per-problem parameters).
    timeout
        Returns the default time-out setting that a solver state would
        be given if it was not directly specified during setup. Value is
        0 if there is no time-out.
    optimizer_param(Param)
        Get the Value of the external solver's parameter Param.
        The exact behaviour and available parameters are dependent on the 
        external solver: if the external solver has only problem specific 
        parameters (e.g. XPRESS-MP 13 and later), this gets the default 
        setting that would be used for new problems; if the external solver
        has global parameters, this gets the global value for the parameter.
        If Param is not a valid parameter for the solver, an out of range 
        error is raised. See lp_get/3 for more details on the parameters.
