Dating sites are a stupid idea in the first place. Your system or algorithm cannot ever hope to compete with 30 seconds of face to face interaction, ideally with that first meeting occurring by way of mutual friends.

Sorry, but building a better dating web site is trying to drive a nail with a screw driver. People who need help dating need a larger and more active social circle. They don't need a dating website. Anyone trying to sell a dating site will inevitably discover they're hawking snake oil and surrender to that reality.
