In this paper we develop several polynomial-time interior-point methods (IPM) for solving nonlinear primal-dual conic optimization problem. We assume that the barriers for the primal and the dual cone are not conjugate. This broken symmetry does not allow to apply the standard primal-dual IPM....

In general, there exist many ways to detect the fair value of financial derivatives. However, each of them is suitable for different purposes. For example, when the payoff function is not very simple or the underlying process is too complex, the approach of Monte Carlo simulation can be useful....

The present paper describes the economic consequences of absenteeism at the workplace, but also the effective methods and strategies for managing it. In this paper, the abstenteeism is considered the failure to report for or remain at work as scheduled, regardless of cause. Recognized holidays,...
