TL;DR: The author argues that the evolution to the fifth-generation computer systems (FGCS) will require advances in pattern recognition and its subareas, not only to achieve man-machine interfaces with a natural mode of communication, but also to implement the basic mechanisms of inference, association and learning, which are inherent inpattern recognition and therefore essential to the core functions of FGCS.

TL;DR: An algorithm for deciding where and when to solve subproblems on a fixed finite network of processors, suitable for search of ordered game trees, and results obtained in practice for one particular problem are given.

TL;DR: A method to formulate the fuzzy information processing approximately by means of the convexly combined fuzzy relational equations is proposed, focusing on the modeling of fuzzy input-output systems, normality of fuzzy sets characterizing fuzzy input, fuzzy logical aspects of systems, and association between fuzzy information.

TL;DR: A conservative consistency and recovery control algorithm for replicated files in the presence of network partitioning due to communication link failures is presented, which supports partial replication, provides nonblocking operations by allowing update access to a file in that file's majority partition, and brings all copies up to date whenever the communication links among them are repaired.

TL;DR: The authors suggest a model of human action in this control system by using fuzzy logic, which consists of fuzzy and nonfuzzy controllers and the double inverted pendulum can be controlled automatically by this model.

TL;DR: A precise formulation of Zadeh's extension principle for fuzzy number theory is given and it is proved that if an equational property p = q holds for the real numbers and the variables occurring in the expressions p and q are distinct, then this property holding for the fuzzy numbers as well.

TL;DR: The method consists of two parts: to obtain several inference results for a given pair of a document and a keyword, and to aggregate them by material implication as well as possibility implication (newly introduced).
