Member Function Documentation

void LinearConstraint::LineSearch	(	const Vector &	x0,
		const Vector &	dx,
		Real &	u
	)

virtual

Given x0 feasible, finds a maximal value u<=u0 s.t. x=x0+u*dx satisfies the constraint. i version: only satisfy the i'th constraint. j version: move in the direction ej. (default uses secant method)

Reimplemented from Math::InequalityConstraint.

bool LinearConstraint::Push	(	Vector &	x,
		Real	d = `Zero`
	)

virtual

Sets x to satisfy the constraint by a margin of d. Returns true on success.

Reimplemented from Math::InequalityConstraint.
