We consider the stochastic (max,+) recurrence
in the case where the sequence
is i.i.d. and multinomial. Based on a decomposition of products of
matrices in blocks of a certain form, we propose upper and lower
bounds for
and the Lyapunov exponent of the system.
The basic computational complexity of the computation is
(N is the size of the matrix) but the accuracy can be
improved at will at the expense of larger computation times.
