 Return the value of the merit function at c(x). This interface requires the client to compute c(x) and pass it to this function to have the value of phi(c) calculated.

 Return the value of the directional derivative of the merit function w.r.t. alpha at alpha = 0. In other words compute return d(phi(c(x)))/d(alpha_k) at alpha_k = 0 where x = x_k + alpha_k * d_k.

Member Function Documentation

virtual value_type ConstrainedOptPack::MeritFuncNLE::value ( const Vector c  )  const [pure virtual]

Return the value of the merit function at c(x). This interface requires the client to compute c(x) and pass it to this function to have the value of phi(c) calculated.

If the merit function has not been initialized properly then a InvalidInitialization exception will be thrown.

Implemented in ConstrainedOptPack::MeritFuncNLESqrResid.

virtual value_type ConstrainedOptPack::MeritFuncNLE::deriv (  )  const [pure virtual]

Return the value of the directional derivative of the merit function w.r.t. alpha at alpha = 0. In other words compute return d(phi(c(x)))/d(alpha_k) at alpha_k = 0 where x = x_k + alpha_k * d_k.

If the merit function has not been initialized properly then a InvalidInitialization exception will be thrown.

Implemented in ConstrainedOptPack::MeritFuncNLESqrResid.

virtual void ConstrainedOptPack::MeritFuncNLE::print_merit_func ( std::ostream &  out,
const std::string &  leading_str 
) const [pure virtual]

Print the merit funciton.

Implemented in ConstrainedOptPack::MeritFuncNLESqrResid.
