Suppose a Decision Maker (DM) makes choices between sets of alternatives. The choice function tool is used to model DM preferences. When the set of alternatives is very large, people generally become confused and cannot handle the information. So, the DM finds it difficult to compare alternatives in such problems. This paper examines how we can help the DM to make choices on a set with a large number of alternatives, when the preference revealed by DM is modelled by a choice function.
