Through online dating applications, social networks, big data analytics, automatic love and breakup letter generators, and other computational intrusions into the private domain, algorithms and artificial intelligence are taking control over the proverbially irrational feeling of love. It might appear enigmatic and impervious to logic, yet the sober perspective of computer science demystifies love and offers well-justified approaches to human relationship problems. Far from challenging the power of artificial intelligence and computation, love has given fertile ground for algorithmic solutions and optimisation procedures. A nuanced, mathematically-inspired look at romance reveals that there are calculable issues and quantifiable outcomes. The latest technological knowledge is now used to establish connections between potential partners and help us make informed decisions when looking for the right match. When it comes to love in the age of artificial intelligence, algorithms organise our relationships and guide partnership choices.
