Heuristics has merits and I think myopic is close to what you describe but
you could take one of these other point of views:

- This is not an algorithm for what you are searching for but for another
not completely specified sub problem that it solves satisfactorily.  Your
new quest is now to characterize this particular problem.

- This is an incorrect algorithm for the problem you want. It is not just
inefficient (hinting that it solves but using too many resources) but has
incorrect outputs.
