The parameters L(e), or P (e), for every observed event e, are computed from the change in the total code-length-the change that corresponds to the cost of adjoining the new event e to the set of previously observed events E: Combining eqs.
1 and 3 gives the probability: P (e) = c(e) + 1 e c(e ) + |E| the cost of the most probable complete alignment of the two words will be stored in the bottom-right cell, V (σ n , τ m ), marked .
