With which bzr version? I would like to test old and new AI and don't know how...

Few comments: AI is very sensitive and complex group of equations and tests and tresholds and so on. One change can fix something but make something else unbalanced. SO - this works somehow, technically it is very aggressive AI, building very strong economy and is expanding slowly. So it work better in restricted rooms. Big free plains are problem (so far). This is something that must be enhanced. My intend is to have some soft treshold, f.e. when player has 100 production buildings, building new production buildings will be slowed down. Of course the threshold (100) should depend on map size or so. This is my intend. It needs testing. Anyway, feedback is welcomed Installation: `bzr branch lp:~tiborb95/widelands/tiborb-ai` and further step should be the same as when compiling trunk. Top Quote

Using the page: https://wl.widelands.org/wiki/BuildingWidelands/#the_fastest_way_to_build_widelands_terminal_use and your clues. After downloading and moving to the folder ~/tibor-ai/ trying to compile it by ./compile.sh Then the error accured: CMake Error at CMakeLists.txt:81 (message): Build-directory and source-directory are the same! How can I solve the problem? Sorry, but I really don't like Linux systems I don't understand them einstein13 calculations & maps packages: http://wuatek.no-ip.org/~rak/widelands/ backup website files: http://kartezjusz.ddns.net/upload/widelands/ Top Quote

The script can be put anywhere, as it is doing 'cd' Top Quote

If you want to profile with valgrind, you have to use its callgrind tool. A tutorial that I always reference is this: http://matt.eifelle.com/2009/04/07/profiling-with-valgrind/ Top Quote

See also https://wl.widelands.org/forum/topic/1484/ Philipp I am far from being finished or satisfied with my modifications to AI, and I have not looked at this problem closer yet. But it would be trivial to code a crude solution like limiting count of the same buildings (f.e. 50 buildings of the type), or limiting proportion of buildings of the same type to all buildings, for example 'no new building of type x if count_of_x>count_of_all_buildings * 0.3' Top Quote
