virtual

Performs the same function as StepBound, and supplies additional information about which component of the nonnegative variables is responsible for restricting alpha.

In terms of the abstract formulation, the components have the following meanings :

primalValue : the value of the blocking component of the primal variables (u,t,v,w). primalStep : the corresponding value of the blocking component of the primal step variables (b->u,b->t,b->v,b->w) dualValue : the value of the blocking component of the dual variables/ (lambda,pi,phi,gamma). dualStep : the corresponding value of the blocking component of the dual step variables (b->lambda,b->pi,b->phi,b->gamma) firstOrSecond : 1 if the primal step is blocking, 2 if the dual step is block, 0 if no step is blocking.
