You may want to make the algorithm more palatable to a general audience by
assigning names to the items and using those, e.g.
NB.* Ullman: return 1 if "t" items of list sum to less than or equal to "k".
Ullman=: 3 : 0
't k lst'=. y
t > +/ k{. /:~ lst
NB.EG Ullman 98.2; 3; 18.1 55.1 91.2 74.6 73 85.9 73.9 81.4 87.1 49.3 88.8
5.7
)
Also, as seen above, it wouldn't hurt to include a comment or two to explain
what this does and give an example of how to use it.
