You could choose to make a decision that is, in relevant aspects, equivalent to simularing Omega. This subjects Omega to the Halting Problem. If you make the Halting Problem irrelevant by limiting time, you’ve also limited Omega’s ability to perfectly simulate you, contradicting the conditions of the problem.
If there are certain algorithms that you just can’t execute due to your limitations, then there may be a logical answer which you are incapable of producing.
Are we supposed to assume that Omega can solve the Halting Problem? Simulating you under some conditions, may implicate it.
(This goes double if you assume “has access to the agent’s source code”.)
There is a time limit so I don’t think the halting problem is relevant here.

Omega has more processing power than you
