Query: RSK correspondence and classically irreducible Kirillov-Reshetikhin
  crystals   We give a new combinatorial model of the Kirillov-Reshetikhin crystals of
type $A_n^{(1)}$ in terms of non-negative integral matrices based on the
classical RSK algorithm, which has a simple description of the affine crystal
structure without using a promotion operator. We also have a similar
description of the Kirillov-Reshetikhin crystals associated to exceptional
nodes in the Dynkin diagrams of classical affine or non-exceptional type.
