Detailed Description

Class to organize all the data required by the algorithm.

Internally, once this Data object has been initialized, all internal curr_ vectors must always be set (so that prototypes are available). The current values can only be set from the trial values. The trial values can be set by copying from a vector or by adding some fraction of a step to the current values. This object also stores steps, which allows to easily communicate the step from the step computation object to the line search object.

The following flag is set to true, if some other part of the algorithm (like the method for computing the barrier parameter) has already computed the primal-dual search direction.

This flag is reset when the AcceptTrialPoint method is called.
