The chapter focuses on the phenomenon of undecidability that was first observed by Church and Turing and shows that simple variations of the techniques of logical description of the meaning of programs lead to far-reaching sharpening of the undecidability theorem. The completeness for the recursively ...
Economic deliberations are slow, effortful and intentional searches for solutions to difficult economic problems. Although such deliberations are critical for making sound decisions, the underlying reasoning strategies and neurobiological substrates rema

1、One of the main problems we face in software development iscomplexity. ─── 在软件开发中我们面对的一个主要问题是复杂度。 2、Then they began to spring up in an increasing numbers andcomplexityeach year. ─── 之后,每年都冒出来更多、更复杂的谷圈。
So, we decided to extend Binary Decision Diagrams technics, which are well suited to the task of solving NP‐hard logic‐based problems. Both theoretical and experimental results are described along this line in the last sections. This is a preview of subscription content, log in via an ...
Obviously, we don’t write software to directly manipulate all relays, instead, we deal with tower of “abstraction”, transistors form logical gates, logical gates form processor, the processor works with machine code, machine code is generated by programmes typically from high-level languages, ...
A second research line has focused on studying the complexity and not on integration of the neural correlates of deduction. Logical complexity is the number of occurrences of logical operators in a cognitive task, while the relational complexity is the number of variables or memory load of that ...

It is often hard to tell whether something that is apparently complex possesses a great deal of effective complexity or reflects instead underlying simplicity combined with a certain amount of logical depth. Faced with a diagram of Mandelbrot’s famous fractal set, for example, we may attribute ...
