Developer will receive an SQL dump of a table with two column, a userid and an object id. The job is to write four efficient algorithms.

recommended_object(int objectid) : returns an array of similar objects and a relevance score per.

recommended_person(int personid) : returns an array of similar people and a relevance score per.

compare_object(int objectid1, int objectid1) : returns a relevance score.

compare_people(int personid1, int personid2) : returns a relevance score based on the user's interests

To bid, please provide two to three sentences on how this is computationally accomplishable.
