  • Patent number: 7065477
    Abstract: A simulation device calculates an equilibrium arrangement of a set of particles by using a potential function or a force function, which describes an interaction of a particle system, and simulates the particle system by using an obtained equilibrium arrangement as an initial arrangement.
    Type: Grant
    Filed: November 5, 1999
    Date of Patent: June 20, 2006
    Assignee: Fujitsu Limited

  • Patent number: 6978245
    Abstract: An automatic planning apparatus comprises a WWW server and an application server which are connected to many clients through the Internet. The clients are operated by the users. The application server creates and asks some questions to the user. The user answers the questions. The answers are analyzed to determine the character. Certain initial conditions are input by the user or some other person. The application server automatically creates a schedule for the preparation of an event desired by the users after taking the input initial conditions and the character of the user into consideration.

  • Patent number: 6735555
    Abstract: A processing device generates a model of a tree in a given arbitrary space, reshapes the tree based on the nodes included in the tree, and outputs a reshape result. By repeating the reshape of the tree while examining the cost value of a reshaped tree, a local Steiner tree with a good cost value is obtained. A network shape is optimized by using the obtained local Steiner tree.

  • Patent number: 6718289
    Abstract: A processing apparatus changes deformation elements composing a shape representing a problem to be processed using a search termination condition, a sequencing algorithm for deformation elements, a cost function and a deformation pattern, and deforms the shape. Then, the processing apparatus searches for a shape with the minimum cost, and outputs the shape as a solution.

  • Patent number: 6697788
    Abstract: In an optimization problem, an optimum solution is searched by using the deterministic dynamics which has a neighborhood search capability, is not trapped into a local minimum state during a search using a search speed control mechanism, and improves the realization probability of the optimum state independent of the search speed.

  • Patent number: 6490583
    Abstract: In a document information processing apparatus handling a large amount of documents, when a document is registered, retrieval data for document retrieval is created for each registered document. Moreover, for each registered document, there is produced an access control table in which information indicating accessibility of groups including users as document retrievers for the document is registered. When a user desires to retrieve a document, accessibility of the user as the retriever is determined in accordance with the access control table for documents retrieved with retrieval data.

  • Patent number: 5887171
    Abstract: A document management system a high extendability, flexibility, and stability capable of solving a problem that, as an agent-oriented paradigm system extends, the number of agents increases and indefinite factors increase. In the system configuration with an object execution environment implemented with an object-oriented function and an agent execution environment implemented with an agent-oriented function, a unit for changing an agent into an object is provided for using the agent execution environment as the object execution environment. With this configuration, a system developer can use the merits of both the object- and agent-oriented paradigms by implementing a function necessary for stable operation by an object and a function with high change occurrence frequency by an agent.
