The application describes parallel solution generation. A data processing apparatus includes a memory including a computer program code, and at least two processors configured to execute the computer program code. The computer program code includes a component program run in parallel on at least two processors to generate solution components compiled in parallel of points, and to store the added solution components in the memory; and a solution program run in parallel on at least two processors to generate a solution by adding one solution component at a time, read from the memory, to the solution based on a key point, and to store the added solution component to the solution in the memory.
