Calculating device

A calculating device, comprising:

• a first memory;
• a second memory;
• a third memory;
• a first arithmetic module;
• and
• a second arithmetic module,
• wherein
• the first memory stores a first variable group {x},
• the second memory stores a second variable group {y},
• the third memory stores a first parameter group {J},
• the first variable group {x} includes N (N being an integer of 2 or more) ith entries of a first variable xi (i being an integer not less than 1 and not more than N),
• the second variable group {y} includes N ith entries of a second variable yi (i being an integer not less than 1 and not more than N),
• the first parameter group {J} includes N×N first parameters Jl,m (l being an integer not less than 1 and not more than N, and m being an integer not less than 1 and not more than N),
• the first arithmetic module update the ith entry of the first variable xi based on the ith entry of the second variable yi,
• the second arithmetic module update the ith entry of the second variable yi based on at least at least a part of the first parameter group {J} and at least a part of the first variable group {x}.
