Usually, as, e.g., in [19], a linesearch is performed along the Gauss-Newton update direction, i.e., [[epsilon].sub.k+1] = [[epsilon].sub.k] + [beta[].sub.k][s.sub.k].

Copy( *xnext ); f_x = feval->ValueRef(); } Display( f,x ); Clean ( ); return TermCode; } // Update lmBFGS inverse Hessian approximation if( ls_result ) // LineSearch failed; reset to steepest descent { // direction H->Reset (); StDescDir = 1; } else { H->Update ( x, *xnext, tmp_eval->GradientRef ( ) , feval->GradientRef () ); StDescDir = 0; } We now compare the performance of this algorithm with the Fortran version (LBFGS) implemented by Nocedal and available from the Netlib software repository.
