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.
