Abstract
A calculation system includes a variable memory storing a value indicating a state of a variable of a mixed integer quadratic programming problem; a state transition calculation block that calculates the next state of the value indicating the state of the variable; a nonlinear coefficient memory that stores a nonlinear coefficient of the state transition calculation block; a linear coefficient memory that stores a linear coefficient of the state transition calculation block; a weight input line that receives a weight signal of the state transition calculation block; and a temperature input line that receives a temperature signal of the state transition calculation block. The state transition calculation block includes a difference calculation block that calculates a difference calculation by using the weight signal, the nonlinear coefficient, and the linear coefficient. A next state determination block calculates the next state of the variable using the value read from the variable memory.
