Engineering Contradiction Analysis
1Productivity
If multiple combinatorial optimization problems are solved sequentially using conventional methods, then each problem can be solved individually, but the total calculation time becomes excessively long
Solution Approach 1:
The patent combines multiple separate combinatorial optimization problems into a single unified problem by merging their respective objective functions and constraints. This allows the annealing machine to solve all problems simultaneously in one calculation process, transforming N separate sequential calculations into one parallel calculation, thereby dramatically reducing total computation time.
Solution Approach 2:
The patent creates a universal optimization framework that can handle multiple different combinatorial optimization problems within a single unified model. By formulating a general-purpose objective function that encompasses multiple specific problems, the system achieves multi-functionality, allowing one annealing calculation to address various optimization tasks that would otherwise require separate dedicated calculations.
2Measurement precision
If separate calculations are performed for each combinatorial optimization problem, then accurate individual solutions can be obtained, but the calculation process must be repeated for each problem
Solution Approach 1:
The patent merges multiple objective functions into a single combined objective function that preserves the essential characteristics of each individual problem. By carefully constructing this unified function, the system maintains solution accuracy for each specific optimization problem while enabling simultaneous solution of all problems through a single annealing calculation process.
