Selective diagnostics for computing systems

A non-transitory computer readable medium comprising computer executable instructions which when executed by a computer cause the computer to perform the method of:

• initializing the adjacency matrix with all zero's, where a row of the adjacency matrix A corresponds to a source diagnostic s of the one or more diagnostics, a column of the adjacency matrix A corresponds to a destination diagnostic d of the one or more diagnostics, and m represents a total count of the diagnostics;
• revising one or more entries in the adjacency matrix A by, for each source diagnostic s, decreasing a corresponding count A(s,d) in the adjacency matrix A to decrease a corresponding directional relation in response to the diagnostic s failing and one or more other diagnostics d passing;
• increasing the corresponding count A(s,d) in the adjacency matrix A to increase the corresponding directional relation in response to the diagnostic s failing and one or more other diagnostics d failing;
• and maintaining a current value of the corresponding count A(s,d) in the adjacency matrix A in response to the diagnostic s passing or having no corresponding data;
• and
• generating the directional relation graph based on the adjacency matrix A.

An apparatus for generating an adjacency matrix A and a directional relation graph representing a relationship between one or more diagnostics, the apparatus comprising:

• at least one processor;
• and
• a memory storing instructions which, when executed by the at least one processor, cause the mobile device to perform a method comprising:
• initializing the adjacency matrix with all zero's, where a row of the adjacency matrix A corresponds to a source diagnostic s of the one or more diagnostics, a column of the adjacency matrix A corresponds to a destination diagnostic d of the one or more diagnostics, and m represents a total count of the diagnostics;
• revising one or more entries in the adjacency matrix A by, for each source diagnostic s, decreasing a corresponding count A(s,d) in the adjacency matrix A to decrease a corresponding directional relation in response to the diagnostic s failing and one or more other diagnostics d passing;
• increasing the corresponding count A(s,d) in the adjacency matrix A to increase the corresponding directional relation in response to the diagnostic s failing and one or more other diagnostics d failing;
• and maintaining a current value of the corresponding count A(s,d) in the adjacency matrix A in response to the diagnostic s passing or having no corresponding data;
• and
• generating the directional relation graph based on the adjacency matrix A.
