See also some papers trying to explain stable marriage as an economic function (as a complex mental process).
They are useless for the Online Dating Industry.
Marital stability does not include marital satisfaction. A marriage can be stable but miserable. Latest Research in Theories of Romantic Relationships Development shows: compatibility is all about a high level on personality similarity between prospective mates for long term mating with commitment.
"online dating" is a broad concept to define a large group of different proposals.

The key to long-lasting romance is STRICT PERSONALITY SIMILARITY and not "meet other people with similar interests".
WorldWide, there are over 5,000 -five thousand- online dating sites
but no one is using the 16PF5 (or similar) to assess personality of its members!
but no one calculates similarity with a quantized pattern comparison method!
but no one can show Compatibility Distribution Curves to each and every of its members!
but no one is scientifically proven!
The only way to revolutionize the Online Dating Industry is using the 16PF5 normative personality test, available in different languages to assess personality of members, or a proprietary test with exactly the same traits of the 16PF5 and expressing compatibility with eight decimals (needs a quantized pattern comparison method, part of pattern recognition by cross-correlation, to calculate similarity between prospective mates.)
High precision in matching algorithms is precisely the key to open the door and leave the infancy of compatibility testing.
It is all about achieving the eighth decimal!
With 8 decimals, you have more precision than any person could achieve by searching on one's own, but the only way to achieve the eighth decimal is using analysis and correlation with quantized patterns.
Without offering the NORMATIVE16PF5 (or similar test measuring exactly the 16 personality factors) for serious dating, it will be impossible to innovate and revolutionize the Online Dating Industry All other proposals are NOISE and perform as placebo.
