int Sepa::HeuristicInnerApproximation::solution	(	double &	solutionValue,
		double *	betterSolution
	)

virtual

Performs heuristic.

Returns a feasible solution to the MINLP The heuristic constructs a MIP based approximating all univariate functions appearing in nonlinear constraints The linear approximation is obtained by adding inner chords linking pairs of points until covering the range of each variable.
