报告提纲:

Abstract : Construction of orthogonal designs (ODs) has received much attention over the past decades, where previous work were originated from either mathematical theory or algorithmic search. A new algorithm is proposed to construct symmetric ODs. It is established on a well-designed framework of sequential construction, combining the deep Q-network (DQN) and orthogonal complementary design (OCD). The DQN-OCD algorithm shows its superiority by constructing various non-isomorphic ODs in an efficient manner. In particular, the constructions of symmetric ODs, including the saturated ODs L₂₇(3¹³), L₂₈(2²⁷) and non-saturated ODs L₁₈(3⁷), L₃₆(3¹³) are presented, where the performance of DQN-OCD algorithm surpasses the others. Furthermore, a series of previously unknown ODs in non-isomorphic subclasses of L₂₈(2²⁷) and L₃₆(3¹³) are constructed as new collections of ODs.
