Wining and dining is the best way for men to woo women, scientists said on Tuesday.

Researchers at University College London developed a mathematical formula and modeled courtship as a sequential game to find the best way to impress the ladies, Reuters reports.

Their results show that offering an expensive present, such as jewelry, signals the man’s serious intentions but he must be wary of being exploited by gold-diggers who will dump him after receiving the gift.

“Guys are less likely to offer expensive gifts to females they don’t have a long-term interest in. And girls won’t be impressed with cheap gifts. By offering expensive but worthless gifts, such as dinner and theatre trips, the male pays no cost if the invitation isn’t accepted,” Peter Sozou, of University College London, reportedly said.

If women are not interested they are unlikely to accept the invitation, according to the research published in the journal Proceedings of the Royal Society of London B.

The researchers said giving gifts was a feature of courtship in humans and other species to impress females. Physical attraction is an important element but offering gifts also helps.

“Our analysis shows there is evolutionary logic in men ‘burning money’ to impress the girl,” Robert Seymour of UCL’s department of mathematics, reportedly said.
