逻辑程序设计语言Gdel与Prolog的比较

A comparison between the logic programming languages Gdel and Prolog

在多态多类的一阶逻辑基础之上,围绕类型系统、模块系统、控制机制、元程序设计和输入/输出部分对Gdel语言功能进行分析.重点比较了逻辑程序设计语言Gdel与Prolog的联系与区别,通过比较分析,表明由于摒弃了Prolog语言中的非逻辑成分,引入了多种新的语言成分,Gdel语言具有更好的说明性语义和执行效率.

We analyzed the functions of the Gǒdel language on the bassis of the first-order logic with polymorphism and multi types. The focus was on its types, module system, control mechanisms, meta-programming, and input/output. Emphasis was on comparisons of relationships and disparities in Prolog and Gǒdel. The comparisons showed that the Gǒdel language is more declarative and efficient because it eliminates the non-logical parts of Prolog and introduces many kinds of new language elements.
