Engineering Contradiction Analysis
1Measurement precision
If manual setting of operating conditions is required, then solution quality can be optimized for specific problems, but user complexity and difficulty of operation increase significantly
Solution Approach 1:
The optimization apparatus automatically adjusts its own operating conditions based on problem characteristics and search results. The system performs self-optimization by modifying temperature schedules, iteration counts, and other parameters without requiring manual user input, thereby achieving high solution quality while maintaining ease of operation.
Solution Approach 2:
The system uses feedback from the search results to dynamically adjust operating conditions. By monitoring the performance and convergence of the optimization search, the apparatus automatically modifies parameters such as temperature schedules and iteration counts to improve solution quality for subsequent searches.
2Device complexity
If fixed operating conditions are used, then device complexity is reduced, but adaptability to different problem types deteriorates
Solution Approach 1:
The optimization apparatus employs dynamic operating conditions that automatically adapt to different problem types. The system adjusts temperature schedules, iteration counts, and other parameters based on the characteristics of each specific optimization problem, enabling versatility without requiring complex manual configuration or increasing device complexity.

AI summary
A problem is inputted into an operation unit. A computation unit searches for a ground state of an Ising model. A management unit converts the problem inputted from the operation unit to the Ising model, inputs the Ising model produced by conversion and initial operating conditions into the computation unit, and has the computation unit search for the ground state using overall operating conditions produced by changing the initial operating conditions based on a result of the computation unit searching for the ground state using the initial operating conditions.
