Calculating device, calculation program, recording medium, and calculation method

A calculation program causing a computer to repeat a processing procedure,

• the processing procedure including a first variable update, a second variable update, and a third variable update,
• the first variable update including updating an ith entry of a first variable xi by adding an ith entry of a first function to the ith entry of the first variable xi before the first variable update (i being an integer not less than 1 and not more than N, and N being an integer of 2 or more), the ith entry of the first variable xi being one of a first variable set {x}, a variable of the ith entry of the first function including an ith entry of a second variable yi, the ith entry of the second variable yi being one of a second variable set {y}, the ith entry of the first function being one of a first function set,
• the second variable update including updating the ith entry of the second variable yi by adding, to the ith entry of the second variable yi before the second variable update, an arithmetic result of an ith entry of a second function, an ith entry of a third function, and an ith entry of a first element function, a variable of the ith entry of the second function including the ith entry of the first variable xi, a variable of the ith entry of the third function including at least a part of a first parameter set {J} and at least a part of the first variable set {x}, a variable of the ith entry of the first element function including a product of the ith entry of the second variable yi and a third variable z, the ith entry of the second function being one of a second function set, the ith entry of the third function being one of a third function set, the ith entry of the first element function being one of a first element function set,
• the third variable update including updating the third variable z by adding an ith entry of a second element function to the third variable z before the third variable update, the third variable z being one of a third variable set {z}, a variable of the second element function including a difference between a first calculation parameter and a mean square of at least a part of the second variable set {y},
• the processor performing at least an output of at least one of the ith entry of the first variable xi obtained after the repeating of the processing procedure or a function of the ith entry of the first variable xi obtained after the repeating of the processing procedure.
