You can still (mis)use: `"renews_map_resource=pond_growing" ( or pond_mature depending on what is output of aqua farm)` though renaming of the hint would be convenient. And together with suggested: `requires_helper = true` would provide what you ask... I think... The bee-keeper is a more difficult case; his supporter building can be one of these (or any combination of): berry farm, reed farm, farm. Perhaps permit supporter to be a table (supporter={frisians_farm, frisians_berry_farm, frisians_reed_farm})? `requires_helper = true` for bee-keeper would be sufficient here as well as long as ANY of supporters is sufficient. Also all supporters would need something like: `"renews_map_resource=honey"` Edited: 2017-08-21, 14:03 Top Quote

I tried to pass a table renews_map_resource={"fruit","honey"} but it resulted in an error message. I´m using the frisian branch for AI training, and I´m merging in the recent changes from trunk quite often, so the source code is the same as in latest trunk, including the AI branches. I have a bit less time for training now than when I started, but I still do one round a day. I can still train the AI for about a week, I don´t know yet whether I´ll still have enough time to continue after that. Anyway, the AI is shaping up great, improvements are clearly visible in every generation, the new AI is much better than the one in b19. I can only say it again: Great work! When playing as Frisians, the AI is much weaker than as any other tribe, however. That is of course due to lack of training as Frisians, but this leads me to another thought: The Frisians are intended to be a tribe for advanced players, with a more complex economy than the other tribes and a higher risk of deadlocks. Can the AI even be as good playing Frisians as the other tribes? Should the same amount of training be put into Frisian AI as into the other tribes, or should it just be accepted that it will never be quite as good with Frisians? Top Quote

In ai this hint is converted to: `int16_t production_hint;` So it is only one number (id of particular ware). Though I can imagine a std::set instead.

I dont know when new release of Widelands is planned, this would be a milestone for AI training. One thing would be convenient to stabilize AI - to slow down mutation rate a bit.

Should the same amount of training be put into Frisian AI as into the other tribes, or should it just be accepted that it will never be quite as good with Frisians? I dont know. AI should be quite generic and training with focus specifically frisians should improve AI for them and not hurt other tribes performance. But indeed there can be specific issues that AI can not overcome. First of all resolve all that missing helper building stuff. Without sufficient information for the AI you cannot expect it would figure things out. Top Quote

I have given up on planning those, since it always takes a lot longer than expected anyway. Any significant changes to AI would cause de-training, so having AI trained now plus this tiny change in production hint would be good opportunity for release. Or we will just wait for release and slowly continually train the AI (Nordfriese mainly) Top Quote
