Using this method proposed here, both executing and candidate paths are generated for the application,the expectation path within candidate paths is found,and then the assumed fault is located by comparing the executing path with the candidate path.

The original LDM algorithm tries to find a set of candidate paths and selects a path with the highest probability from the candidate path set to assign a flow.

Using this method proposed here, we generate both executing and candidate paths for the application, finding the expectation path within candidate paths, and then to locate the assumed fault by comparing the executing path with the candidate path.
