A sequential quadratically constrained quadratic programming method for differentiable convex minimization
by Masao Fukushima, Zhi-Quan Luo and Paul Tseng
This paper presents a Sequential Quadratically Constrained Quadratic
Programming (SQCQP) method for solving smooth convex programs.
The SQCQP method solves at each iteration a subproblem that involves
convex quadratic inequality constraints as well as a convex quadratic
objective function. Such a quadratically constrained quadratic programming
problem can be formulated as a second-order cone program,
which can be solved efficiently by using interior point methods.
We consider the following three fundamental issues
on the SQCQP method: the feasibility of subproblems, the global convergence,
and the quadratic rate of convergence. In particular, we show that the
Maratos effect is avoided without any modification to the search direction,
though we use an ordinary $\ell_1$ exact penalty function as the line search
