## Variable metric methods for a class of extended conic functions.(English)Zbl 0548.90062

The paper contains a description and an analysis of two variable metric algorithms for unconstrained minimization which find a minimum of an extended conic function after a finite number of steps provided it is possible to compute the derivatives of the model function at an arbitrary point $$x\in R_ n$$. Moreover, the developed theory is applied to a special class of the exponential type of extended conic functions.
