A transposition error may occur in a voting machine when the voting machine switches candidates so that votes are counted for a different candidates than a voter intended. Such transposition errors may occur due to either intentional manipulation (e.g., a bad actor hacking the voting system, etc.), or unintentional human error (e.g., an unintentional human error in computer programming, etc.). In some embodiments, a 'minimum test deck' is created that includes the minimum number of filled out ballots that will effectively test a voting machine to ensure that no transposition error occurred.

Robust election logic and accuracy

The following relates generally to error detection in voting systems, and, in particular voting systems using optical scan machines. In some embodiments, one or more processors are configured to: (1) capture, with an optical scan machine, original image data; (2) isolate a first subimage of the original image data; (3) associate the first subimage with a first configuration file candidate, wherein the first configuration file candidate is indicated by a configuration file configuring the optical scan machine, and wherein the association is done according to the configuration file; and (4) display the first subimage along with a representation of the first configuration file candidate.
