Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Comparing disparate data in complex data structures is challenging due to the need for different comparison methods for various data types, which complicates determining equivalence between simulation and executable results in technical computing environments.
Innovation Solution
A comparator API is provided that recursively compares all elements of a data structure using appropriate comparison logic for each element type, supporting data structures like cell arrays, structure arrays, numeric, logical, string, and object data, enabling equivalence testing between simulation and executable results.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If different comparison methods are used for various data types, then measurement precision is improved, but device complexity increases
Solution Approach 1:
The patent implements a universal comparator API that can handle multiple data types (numeric, logical, string, cell arrays, structure arrays) through a single unified interface. The comparator uses recursive comparison logic that automatically adapts to different data types, eliminating the need for separate comparison methods for each type while maintaining high precision for all data formats.
Solution Approach 2:
The patent changes the parameter of comparison logic from type-specific fixed methods to a dynamic recursive approach that automatically selects appropriate comparison strategies based on the actual data type encountered. This allows the same comparator structure to handle diverse data types with appropriate precision without increasing complexity.
2Measurement precision
If recursive comparison of all elements is performed, then measurement precision is improved, but loss of time increases
Solution Approach 1:
The patent segments the comparison process into hierarchical levels, comparing data structures element-by-element through recursion. By dividing complex data structures into smaller comparable units and processing them systematically, the patent achieves thorough equivalence determination while maintaining efficient execution through the segmented approach.
Solution Approach 2:
The patent implements early termination logic that stops the recursive comparison process as soon as a difference is detected, rather than examining all elements. This partial action approach maintains measurement precision by ensuring complete comparison when needed while significantly reducing time loss when data structures differ at early levels.
3Device complexity
If a single comparator API is used for all data types, then device complexity is reduced, but adaptability decreases
Solution Approach 1:
The patent designs the comparator API with universal functionality to handle numeric, logical, string, cell arrays, and structure arrays through a unified interface. The recursive comparison logic automatically adapts to different data types, providing high versatility while maintaining simple device structure from the user perspective.
Solution Approach 2:
The patent implements dynamic adaptation within the single comparator API, where the comparison logic automatically adjusts its behavior based on the data type being compared. This dynamic capability allows the same simple interface to handle diverse data types effectively, maintaining both low complexity and high adaptability.

AI summary
A device receives a first result that includes first data, and a second result that includes second data, and determines whether a comparator supports the first data and the second data. When the comparator supports the first data and the second data, the device utilizes the comparator to select comparison logic for the first data of the first result and for the second data of the second result, compares the first result and the second result, using the selected comparison logic, to determine whether the first result is equivalent to the second result, and outputs or stores the determination of whether the first result is equivalent to the second result.
