Also I should add, being a Factorio veteran with 2-3k hours in this game, I think the goal of making the "largest possible factory" is too vague and not the right metric. When Factorio players make large megabases, they don't go for "size" per se, but rather science research per minute. The metric you should be telling the agents is SPM, not "largest" base!

Put machine #1 at the starting location, run in one direction, and put machine #2 just before time runs out.
This is going to be a huge factory (as measured by its bounding box) but it's not super interesting.
