所有编程语言都提供抽象机制。从某种程度上来说，问题的复杂度直接取决于抽象的类型和质量。这里的“类型”意思是：抽象的内容是什么？汇编语言是对底层机器的轻微抽象。接着出现的“命令式”语言（如 FORTRAN，BASIC 和 C）是对汇编语言的抽象。与汇编相比，这类语言已有了长足的改进，但它们的抽象原理依然要求我们着重考虑计算机的结构，而非问题本身的结构。

程序员必须要在机器模型（“解决方案空间”）和实际解决的问题模型（“问题空间”）之间建立起一种关联。这个过程既费精力，又脱离编程语言本身的范畴。这使得程序代码很难编写，维护代价高昂。同时还造就了一个副产业——“编程方法”学科。

为机器建模的另一个方法是为要解决的问题制作模型。对一些早期语言来说，如 LISP 和 APL，它们的做法是“从不同的角度观察世界”——“所有问题都归纳为列表”或“所有问题都归纳为算法”。PROLOG 则将所有
问题都归纳为决策链。对于这些语言，我们认为它们一部分是“基于约束”的编程，另一部分则是专为
