Forget expensive presents or costly jewelry. Wining and dining is the best way for men to woo women, British scientists said Tuesday.

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

Their results show that offering an expensive present 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 theater trips, the male pays no cost if the invitation isn��t accepted," said Dr Peter Sozou, of University College London.

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.
