class Mechatronix::BarrierLog0 : public Mechatronix::RegularizedBase

Barrier function class

This class implement a smooth approximation of the ideal barrier class \( b(x) \) where ideal barrier satisfy \( b(x)=\infty \) for \( x<0 \) and \( b(x)=0 \) for \( x>0 \).

Inizialization

inline explicit BarrierLog0()

virtual void setup(GenericContainer const &gc) override

Initialize regularization parameters with a GenericContainer. Expect to find gc("h") containing a real scalar.

void setup(real_type h)

Initialize regularization parameters \( h \).

Set the parameter \( h>0 \) for the barrier function.

This parameter is used to define barrier \( b(x) \) in such a way \( b(h)=0 \). Moreover \(b(0)=\infty\) and \( b(x) = 0 \) for \( x \geq h \).

inline void update_h(real_type h)

Update regularization parameter \( h \).

Evaluate
