A calculation processing apparatus includes a monitor, a CPU, a memory and a hard disk. The hard disk stores an initial program input from outside, a network creation program, a network modifying program, network information, node operation definition, and learning variables. The CPU executes the network creation program, and creates network information related to a network representing an algorithm structure of the initial program. Further, the CPU executes the network modifying program and modifies the network information based on the result of calculation by the network, using a learning algorithm.
