Query: On Frenkel-Mukhin algorithm for q-character of quantum affine algebras   The q-character is a strong tool to study finite-dimensional representations
of quantum affine algebras. However, the explicit formula of the q-character of
a given representation has not been known so far. Frenkel and Mukhin proposed
the iterative algorithm which generates the q-character of a given irreducible
representation starting from its highest weight monomial. The algorithm is
known to work for various classes of representations. In this note, however, we
give an example in which the algorithm fails to generate the q-character.
