A planning means generates a plan to be executed by agents on a node. In the case where the plan generated uses an uncertain knowledge required to be processed in other nodes, a judging means judges the communication line connecting the node and a network is low or high in reliability. In the case where the reliability of the communication line is low, an agent management unit moves the agent for executing the plan to another node for processing the uncertain knowledge. In the case where the reliability of the communication line is high, on the other hand, a cooperation protocol realization means requests an agent on another node to process the uncertain knowledge. An agent execution means executes the plan generated.

A planning section generates a plan to be executed by agents on a node. In the case where the plan generated uses an uncertain knowledge required to be processed in other nodes, a judging section judges the communication line connecting the node and a network is low or high in reliability. In the case where the reliability of the communication line is low, an agent management unit moves the agent for executing the plan to another node for processing the uncertain knowledge. In the case where the reliability of the communication line is high, on the other hand, a cooperation protocol realization section requests an agent on another node to process the uncertain knowledge. An agent execution means executes the plan generated.

Method and apparatus that improves the technique by which a plurality of agents process information distributed over a network through by way of a contract net protocol

In a data-processing apparatus, in local information storage L and R at each node, local information for the purpose of accessing a constituent element is stored, this information being updated. A plan is generated that represents the action that should be taken by an agent in order to satisfy request code that has been input, this being generated as a set of actions, based on agent information and local information. The operation of the agent is implemented at the nodes L and R, based on the various actions that make up the thus-generated plan, and an agent is migrated to another node, based on a go action within the plan. It is possible to perform replanning and generation of a child agent at a migration destination node, if necessary, because of the failure of plan execution, for example.

A multi-head disk recording and reproducing apparatus, wherein sector synchronization signals obtained from a first optical pick-up and a second optical pick-up are input to a phase comparator where phases are compared, and a preceding sector synchronization signal is output to an overall control unit. In the overall control unit, the processing is carried out with respect to a first optical pick-up and second optical pick-up by a procedure using this input preceding sector synchronization signal as a reference. First, during a term where addresses are determined in the pick-ups, a sled servo and a spindle servo operation are carried out with respect to each pick-up. When the maximum time t of phase deviation has elapsed and addresses are determined, a tracking servo, focus servo, laser control, and other operations are instructed to the control units based on the addresses.

A constraint-based spreadsheet system includes a direction discrimination section, a dependence information generating section, a program execution process information generating section, and a display section. The direction discrimination section discriminates whether constraint information, which corresponds to a formula which is a basic structural element of a program, has direction of calculation. The dependence information generating section generates dependence information between tables and within a table based on the direction of calculation discriminated by the direction discrimination section. The program execution process information generating section generates program execution process information using the dependence information. The display section displays the program execution process information.

A tape tension controlling circuit which eliminates a complicated controlling operation and is produced at a very low cost. A supply side tape tension regulator is provided on the supply reel side while a take-up side tape tension regulator is provided on the take-up reel side with reference to a rotary drum, and displacements of the regulators corresponding to tension values of the magnetic tape are fed back to reel controlling systems for the supply reel and the take-up reel so that the tape tension on the supply reel side and the tape tension on the take-up reel side are individually kept constant. When the magnetic tape is to be fed in a pinch-off condition wherein a pinch roller is spaced away from the magnetic tape, a take-up side tension error signal is inhibited from being supplied.
