20.18 Extensions of the Approach The approach can be extended so that there are no limits on the number of alternative values of the path function at a node The basic idea is that it is not necessary to consider every possible value of the path function It is sufficient to consider a relatively small number of representative values of the function at each node Options, Futures, and other Derivatives, 5th edition 2002 by John C.
