Abstract: Provided is a system including a plurality of correlated function blocks, for executing load balancing among the function blocks. The plurality of function blocks each include an activation/shutdown control unit to determine whether to activate/shut down its own function block based on information of an evaluation function of its own function block and information of an evaluation function of another function block that has a relation to its own function block, and the activation/shutdown control unit determines whether to activate/shut down its own function block by using an amount relevant to the evaluation function of its own function block in a state where the evaluation function of its own function block takes a desired value, and using a state of the evaluation function of the another function block having a relation to its own function block that is equivalent to, or related to, the relevant amount.

Abstract: An object is to provide a system in which components can overall operate in concert with one another by using only functions about the components, without using the theory of probability. The system includes a plurality of function blocks correlated to one another.
