Towards the distribution of the smallest matching in the Random   Assignment Problem
  We consider the problem of minimizing cost among one-to-one assignments of $n$ jobs onto $n$ machines. The random assignment problem refers to the case when the cost associated with performing jobs on machines are random variables. Aldous established the expected value of the smallest cost, $A_n$, in the limiting $n$ regime. However the distribution of the minimum cost has not been established yet. In this paper we conjecture some distributional properties of matchings in matrices. If this conjecture is proved, this will establish that $\sqrt{n}(A_n - E(A_n)) \overset{w}{\Rightarrow} N(0,2)$. We also establish the limiting distribution for a special case of the Random Assignment Problem.
