virtual void DecompApp::initDualVector ( std::vector< double > & dualVector )

inlinevirtual

Initialize the dual vector for PhaseII of PC.

The user is passed a reference to the internal data and can manipulate it directly.

This is only called when dual stabilization is used, i.e., when m_param.DualStab > 0, at the first iteration of PhaseII of PC. The vector is immediately smoothed with the initial restricted master duals. By default, the restricted mater is used as the initial dual and, therefore, no smoothing occurs in the first iteration.

Definition at line 282 of file DecompApp.h.

virtual bool DecompApp::APPisUserFeasible	(	const double *	x,
		const int	numCols,
		const double	tolZero
	)

inlinevirtual

Method to determine if the solution (x) is feasible to the original model.

For explicitly defined model components, like the model core constraints (A''), the feasibility of the solution is automatically checked against the constraints. In the case when the relaxed problem constraints (A') are explicitly defined - these are also checked automatically.

However, for some applications, a valid feasible constraint system cannot be explicitly defined (even for the core set of constraints). For example, think of the case of TSP, where A'' is defined as the subtour elimination constraints. These constraints are implicitly defined by deriving the method DecompApp::generateCuts. Therefore, the framework cannot automatically tell if a solution is feasible by checking against the constraint system. In this case, the user must provide this method.

Parameters

[in]	x	The solution point to check.
[in]	numCols	The number of variables.
[in]	tolZero	The integrality tolerance (currently ignored).

Returns: True, if x is feasible; otherwise, false.
