Summary. We show that, in the usual probabilistic model for the random assign-
ment problem, the optimal cost tends to a limit constant in probability and
in expectation. The method involves construction of an infinite limit structure,
in terms of which the limit constant is defined. But we cannot improve on
the known numerical bounds for the limit.

1 Introduction
In the deterministic assignment problem, there are n jobs, n machines and a
n x n non-negative matrix (tj,,,) representing the cost of performing job j on
machine m. An assignment is a permutation ~ of {1, ..., n}, indicating that job
j is assigned to machine ~(j). The optimal assignment has cost min~tj,~(j),
