Topic: AI not building enough smelting works

However, this seems to be a problem for the AI: The AI will build exactly 1 smelting works, which will operate at 65% (maximum when there is enough iron ore and coal). Even though the AI economy is starved for iron, and there is plenty of iron ore and coal, the AI will not build further smelting works. The AI will only start building more smelting works after it finds gold ore. Philipp Top Quote

There were major changes with AI since build-18. einstein13 calculations & maps packages: http://wuatek.no-ip.org/~rak/widelands/ backup website files: http://kartezjusz.ddns.net/upload/widelands/ Top Quote

AI limits the number of constructionsites, so this might be an reason - too many unfinished sites 2. First building of a kind is forced, regardless of above, but second and next ones depends statistic of current buildings. And here can be a problem. Especially the fact that it produces multiple outputs and so far statistics provides only one agregate number (much lower then 100%) and it seems that there is still some available capacity... I will rethink it, but in next branch, not the one I am finishing now.. Top Quote

It seems that production buildings are programmed the way that they are idle when particular output can not be produced, even though it might be producing another output instead. If it the really true, this is another complication for AI. I will have to look directly at productionsite's code to see if this can be worked around and how straightforward it could be. Top Quote

Tibor Joined: 2009-03-23, 22:24 Posts: 1377 One Elder of Players Location: Slovakia	Posted at: 2015-03-24, 16:21 No But I made some small change in the code that would mitigate the problem. But still testing and observation is needed to see how effective it was. But it is not in trunk yet. Top Quote
