In the spirit of cultural confidence

this paper presents thirty-six stratagems of schemes and thirty-six stratagems of algorithms for computer system design after learning I Ching in depth and digging out the abstract and inferential concepts of the image thinking of I Ching. Which combines the development of modern computer science and the author's own professional experience. It proposes four basic relations of unity of opposites in computer science (i.e.

four basic scientific problems)

which include: The positioning of centralization and decentralization

the interaction of hardness and softness

supply-demand correspondence and serial-to-parallel conversion. From the perspective of the positioning of centralization and decentralization

eighteen stratagems of architecture design are proposed in the thirty-six stratagems of algorithms

which include the stratagems of time-space transformation and various computing modes. From the perspective of the interaction of hardness and softness

eighteen stratagems of system features are proposed in the thirty-six stratagems of schemes

which include the stratagems of designing eight kinds of features

such as controllability

efficiency

security and variability. The scientific problems involved in supply-demand correspondence and serial-to-parallel conversion are mainly embodied in the thirty-six stratagems of algorithms for resource management and task scheduling. These algorithms and schemes include classic and hot issues in computer science

such as computability

multi-objective optimization

cloud computing

software defined system

big data thinking and artificial intelligence. The thirty-six stratagems of schemes and thirty-six stratagems of algorithms can provide computer professionals with thinking framework

dialectical thinking and necessary stratagems and instances in learning and developing computer systems. More importantly

they can help the computer professionals further understand the philosophical principles of things.
