WebApr 30, 2014 · The fundamental idea of all active-set methods is to fix a working set, a maximal linearly independent subset of the active constraints, and to solve the resulting equality constrained QP problem. The working set is then updated repeatedly until optimality is reached. Active-set methods can be divided into primal, dual, and parametric methods.
