Mathematics is probably not a subject that many people find sexy, but it could hold the key to finding true love.
Mathematicians have developed a series of theories that can help people find the perfect partner.
These include tips such as not trying to hide the less attractive parts of your appearance in your online dating profile pictures and looking for people who had fewer colds as a child.
They have also proposed mathematical approaches to finding the perfect wife or husband - by not choosing to settle down until after the age of 22 years old.
Dr Hannah Fry, a lecturer at University College London and author of a new book on The Mathematics of Love, outlined the theories at the Oxford Literary Festival.
She said that choosing friends who are slightly less attractive than you when going out looking for love could also bring advantages.
This is known as the Discreet Choice Theory, where the presence of an irrelevant alternative can change how you view your choices.
THE MATHEMATICS OF FINDING TRUE LOVE
In her book, Dr Hannah Fry suggest a number of techniques to help people find true love.
Have friends who are less attractive than you: Known as Discreet Choice Theory, the idea is that if there are two women - A and B - who men rank as being equally attractive, if a third woman comes along who looks like a less attractive version of woman A, then woman A becomes more popular with the men.
Highlight your flaws: Analysis from dating websites has shown that often it is not those who are rated the 'most attractive' who get the most responses from other users.
Instead it appears to be those that divide opinion - so those that have something that sets them apart from the rest of the crowds.
Men with bald heads, for example, should not wear a hat to cover their pate as their lack of hair will be attractive to some. Those who are overweight should also not use clever photo cropping to hide what they perceive as flaws.
This means people who find these traits attractive will face less competition than messaging those who have 'perfect' profile pictures.
This formula produced by psychologist John Gottmann and mathematician James Murray predicts how positive or negative a wife and husband will be when they respond in the next turn of a conversation. The most successful couples are those that allow each other to complain and don't let trivial problems build up.
这个公式是由心理学家John Gottmann和数学家James Murray共同完成的，预示了妻子和丈夫在下一段对话中会有多么正面或消极。最成功的夫妇是允许对方抱怨并不会让生活琐事升级成严重问题的人。
Choose 'healthy' looking partners: Dr Fry also explained that looking for those who tend to be heathlier are also likely to be more attractive.
Don't settle down until 37% of your 'dating period' has past: The Optimal Stopping Period theory dictates that people should only start looking for the partner they want to settle down with after 37 per cent of their 'dating period' has past.
If, for example, they are looking to get married by the age of 35 years old, and start dating from the age of 15, they should discount all partners they have before the age of 22.4 years old.
After this time has past, marry the first 'best' partner you get: After the 37 per cent period has past, Dr Fry said people should marry the first partner they find that is better than any that came before.
