1橘黄火焰被漆黑铁栅包围着,在猩红的木柴上不安份地舞蹈,照亮周围。我用手拨起散落的发梢,朝禁闭的窗台走去。木制地板在我脚下发出吱嘎的声响,经过炉火时舒适的暖意,窗台的冰冷坚硬,一切都是这么真实,甚至窗外落雪的微妙触感都能完美模拟,但我仍旧不能把它们当成真实,因为我所迈出的每一步,那种陌生而又熟悉的感觉总是如影随形,提醒... 相似文献

In this paper, we show that the classical A.I. planning problem can be modelled using simple database constructs with logic-based semantics. The approach is similar to that used to model updates and nondeterminism in active database rules. We begin by showing that planning problems can be automatically converted to Datalog1S
programs with nondeterministic choice constructs, for which we provide a formal semantics using the concept of stable models. The resulting programs are characterized by a syntactic structure (XY-stratification) that makes them amenable to efficient implementation using compilation and fixpoint computation techniques developed for deductive database systems. We first develop the approach for sequential plans, and then we illustrate its flexibility and expressiveness by formalizing a model for parallel plans, where several actions can be executed simultaneously. The characterization of parallel plans as partially ordered plans allows us to develop (parallel) versions of partially ordered plans that can often be executed faster than the original partially ordered plans. 相似文献

The broad range of capabilities exhibited by humans and animals is achieved through a large set of heterogeneous, tightly
integrated cognitive mechanisms. To move artificial systems closer to such general-purpose intelligence we cannot avoid replicating
some subset—quite possibly a substantial portion—of this large set. Progress in this direction requires that systems integration
be taken more seriously as a fundamental research problem. In this paper I make the argument that intelligence must be studied
holistically. I present key issues that must be addressed in the area of integration and propose solutions for speeding up
rate of progress towards more powerful, integrated A.I. systems, including (a) tools for building large, complex architectures,
(b) a design methodology for building realtime A.I. systems and (c) methods for facilitating code sharing at the community
level.
