Henceforth, we refer to this computation as State Space Traversal (SST) [9]. Note that SST describes a computational framework (that is, a setting within which a family of computations sharing a set of properties can be defined) rather than a specific computational problem. Variants of this computational framework are discussed in Section 7. It may be helpful in what ....

....During the past decade, expert systems have become the first practical application of artificial intelligence. However, many expert system applications are rule based systems, which require a time consuming and difficult knowledge acquisition process to extract expertise from domain experts [1 3]. Neurocomputing is the application of artificial neural networks to practical problems. An artificial neural network consists of processing elements (which is analogous to neurons in the biological neural system) in an interconnected network [4 11] Aprocessing element accepts inputs, ....

....filled with other object s) for control flow, for data flow, for object decomposition, and for abstraction and refinement to other objects. Production rules are the most popular knowledge representation technique. They are very suitable to represent heuristic knowledge as situation action pairs [8,10]. XRL rules are implemented as objects. This implies that rules may be related in inheritance hierarchies similar to concept taxonomies. For example, the set of rules that detects which are the usages of an array in a program has the following structure: RULE STORE SORT STACK QUEUE ACCUM ....

Associated with this architecture, a refinement language is defined. For example, the generic object description below is a declarative specification of a procedure for the addition of the positive elements from ....

....P2(1) is that any occurrence of a P1 at level 3 followed by a P2 at level 1, will cause the event, and that the lengths of these events are not significant. This pattern generating process is similar to the one used in the Chemical structural generator of Stanford s DENDRAL project in the 70s, [4]. Experiment C: The algorithm was used to generate patterns for several patient events, and we asked several clinicians to eliminate patterns (patterns of physiological events) which they thought would be impossible or very unlikely. If we are able to eliminate a sizable number of patterns then ....

....simple solutions is by including a complexity penalty in the evaluation function. 2. 1 Why procedural representations A representation of knowledge is a combination of data structures and interpretive procedures that, if used in the right way in a program, will lead to knowledgeable behavior [Barr and Feigenbaum, 1981]. Two particular types of representation have played an important role in the development of AI ideas: declarative and procedural representations. A natural question is why use procedural representations when the field of symbolic AI, at least, has apparently moved from procedural representations ....

....within such a theory. The best known language for a formal model is first order logic which expresses facts and rules in a single, formalized matter [Gallaire 1984b] and derives knowledge by using formal rules. The deductive power of logic inference systems is typically used in AI systems (Barr 1982] [Hayes Roth 1983] Geographic Information Systems need these methods to help integrate data from different sources into a unified system [Robinson 1987a] A deficiency of any AI based system is the quantitative difference between AI expert systems and database management systems [Mylopoulos ....

However, the representation of functionality must both consider the aspects defined but also capture the description of the interaction. 5 A review of these forms of knowledge representations can be found in [4]. 11 A functionality class refers not only to a group of objects but also to the actions employed in the application of the object, the feedback used to control and monitor the interaction as well as possible action to verify whether the functional interaction was successful. In the case of ....

We are using the phrase open to represent the set of possible next moves as used in the AI literature on search algorithms (see [7], for example) If a node under consideration is opened, then we shall, perhaps at a later time, investigate the possibility of the desired shortest path going through that node. If the bounds indicate that the desired shortest path cannot pass through the node, it is not opened. 3 The issue ....

Some generalizations and related issues have been discussed in Section 6. We present our conclusions in Section 7. 2. DOMAIN ENCODING In the state space search paradigm [7], to find the solution of a problem, a search algorithm starts from one or more initial states and finds paths to the goal states. In the absence of any criteria for determining whether an intermediate node should be explored (opened) the number of nodes explored before arriving at a solution is ....
