===Results and discussion===
With the developed program, multiple artificial DNA kits which have 2000 SNPs in each chromosome were created. Unfortunately, all of these DNA kits have 0 matches with other DNA in the public database which means these artificial DNA kits do not relate to any kit in the GEDmatch database.
[[File:zero_match.png|thumb|600px|center|Figure 9: match results of artificial DNA(replace empty SNPs with random pairs to 2000 SNPs in each choromosone)]]
Then kits with more amount of empty SNPs were replaced with homozygous pairs or random pairs were created, but none of these files could find relative DNA kits in the database. Even the DNA kits with all empty SNPs recovered could find a matched DNA result. It is important to note that all 5 recovery strategies were all implemented.
As GEDmatch is the most commonly used DNA database in public, it contains a huge amount of DNA kits in its database. As the website shown, the total number of kits managed by GEDmatch database is 1363427157376. Therefore, the chance that no DNA kit in the database is related to Somerton Man is nearly impossible. This means that the quality of Somerton Man's DNA file is too low to be used on the one-to-many tool and implementing simple recovery algorithms are pointless.
