So I use some numerical algorithms in Excel and LAMBDA gives a great approach when iteration is necessary. However, I have found two approaches that can be good in practice. One uses REDUCE to essentially emulate a For Loop while the other uses recursion. I am curious what the general consensus is on which of these is "better" as a standard of practice. Better could mean anything from performance to stability to maintainability to readability and so on. I do expect that which is better will depend meaningfully on the problem in question - some problems will probably lend themselves naturally to one approach or the other. For the purposes of this post, I am thinking of the problem space as be
