honestly i find this hard to read as well, esp. compared to traditional C-like syntax:
if(bx<=20) if(py<=by && py+60>=by) return 0; else return 1; if(by>=415) return 2; else return -1; if(by<=0) return 4; else if (by>=500) return 5;
Yes, Max/MSP's [if] object has a more readable syntax. Yet even with the two nested "ifs" I find it easier to read than your implementation because I don't have to look up to the inlet to remind myself which list elements correspond to which variable.
I could put comments closer to each object chain, but then that's even more objects.
and as a matter of fact, i don't think the pd-implementation of the algorithm is so bad.
Yes, IMO the way you implemented it is nice because there are very few wires crossing over objects.
I'd also mention I find it more difficult to patch your implementation because there are 25 objects (not including the number boxes), 16 of which correspond to the args of [expr] in my implementation. That's 16 objects for which I have to change modes between the mouse (for connections) and the keyboard (for text).
With [expr] I find it conceptually easier (and more ergonomic) to set up my [v] objects, my [sel], and my [outlet], then code the entire algorithm inside one box.
Btw- you can get rid of 3 overlapping wires if you put [value py] closest to [unpack 0 0 0] and cascade them that way.

the only awkwardness in my implementation i find is the [*-1]->[moses 0] , which one could simply replace by [moses -1] (supposed we don't care about values between -1 and 0) (or with a [<=0]->[select 1] which i didn't do for conceptual reasons)
