How about this:

If you have a set E = {X, Y, Z...} of possible actions, A (in E) is the utility-maximising action iff for all other B in E, the limit

is greater than zero, or approaches zero from the positive side. Caveat: I have no evidence this doesn't implode in some way, perhaps by the limit being undefined. This is just a stupid idea to consider. A possibly equivalent formulation is

The inequality being greater or equal allows for two or more actions being equivalent, which is unlikely but possible.

Side comment: that math equation image generator you used is freakin' excellent. The image itself is generated based from the URL, so you don't have to worry about hosting. Editor is here.
