What is copelands method?

Copeland's method is a voting system that assigns points to each candidate according to how many other candidates they outrank in pairwise comparisons. In this method, every candidate is paired with each of the other candidates, and voters decide which of the two candidates they prefer. The winner of each pairwise comparison earns one point.

If two or more candidates tie, they each receive half a point. The candidate with the most points at the end of all pairwise comparisons is declared the winner.

Copeland's method is a simple and easy-to-understand voting system that provides a good balance between simplicity and accuracy. However, it has been criticized for not always producing a unique winner, especially when there is a tie between multiple candidates. Additionally, it can sometimes result in a candidate being elected who is not the most preferred by a majority of voters.
