Abstract :
In this paper, we propose a new barrier function for optimization problems with integral quadratic constraints (IQC). The new barrier function is used to construct an interior point algorithm, which solves IQC optimization problems in a more efficient fashion. Numerical tests as well as worst-case computational complexity analysis are performed to evaluate the efficiency of the proposed algorithm.
