What is Stable Marriage Algorithm?
A mathematical method that brings together items from two different groups in a way that provides the most optimal matching for each other.
Overview
There are some matching problems in life where everyone has a favorite candidate, but not everyone can get the best one. Known as the stable marriage problem, this algorithm examines two-sided sets of preferences to find a balanced compromise point where no one will say 'I wish I had chosen the other.'
How it works
It begins with everyone in the groups ranking the candidates belonging to the other group according to their own preferences. Step-by-step rounds of proposing and rejecting are conducted, and matches are updated until the system reaches a stable state.
Where it is used
It is used in organ donation matchings, university quota placements, and recruitment processes to bring together candidates and positions in the most suitable way.
Questions and answers
Does it yield a perfect result for everyone?
Not perfect, but it yields the most stable and hardest-to-break balanced result according to the preferences of the parties.
Does it only match humans?
No, it is also used in computer science to match objects such as servers and data packets.
