Action Description Language (ADL)¶
使用对象类型和某些ADL功能的一些示例。
The Action Description Language (ADL) (Pednault, 1994) extended STRIPSal-lowing actions to have conditional effects, so some effects are triggered depending on the state. In contrast to STRIPS, ADL allows existential quantification, negative literals, goals with disjunctions, different object types, and while variables in STRIPS are either true or false, in ADL they can be true, false or undefined.
称为ADL的语言（动作描述语言）增加了对STRIPS的许多不同扩展的支持：否定前提条件（如果不携带任何东西，则只能从A移到B），析取前提条件（如果满足条件，则只能乘火车旅行）您有钱或已经有票），析构目标（您想拥有汽车或摩托车）以及其他一些扩展。您可以使用（：requirements：adl）请求完整的ADL表达 。
In the year 1998, with the aim to make a standard representation of planning languages, the Planning Domain Definition Language (PDDL) (McDermott et al.,1998) was published. The IPC has been used to compare planning solvers performance but also to include new features to the language.
