Abstract: Provided is an optimization method including executing a ground state search for an interaction model by a ground state search in a surrogate interaction model including D (D is a natural number of three or more) variable groups each having N continuous variables by using an information processing apparatus, the interaction model having a third-order or higher-order energy function including N (N is a natural number) continuous variables and discrete variables. The ground state search is executed based on simulated annealing. An interaction relation of the surrogate interaction model has a complete D-part graph structure.

Abstract: For any weight change of items in a combination of discharge-target weighing conveyers selected by combinatorial computations during a standby state before the conveyers start to be driven, the combinatorial computations are executed again to select a new combination of discharge-target weighing conveyers, so that the items on the selected weighing conveyers that changed in weight are not transported to a collection conveyer without being possibly reselected into the new combination of conveyers. For any weight change of the items in the combination of discharge-target weighing conveyers during a transport-active state after the conveyers start to be driven, at least one of the collection conveyer or the weighing conveyer subject to the weight change is no longer driven or driven in an opposite transport direction, so that the items on the selected weighing conveyers that changed in weight are not transported into a packaging machine subsequent to the collection conveyer.

Abstract: An enclosing device includes an envelope conveyance path, an envelope loader, an envelope-position restrictor, and an envelope-position adjuster.

The envelope-position adjuster adjusts a position of the envelope with respect to a conveyance direction of the envelope while maintaining a state in which the envelope-position restrictor restricts the loaded position of the envelope.
