Subject: Kalah thread
There was a question about Kalah rules. You should use the rules described in the introduction section on the Wikipedia page https://en.wikipedia.org/wiki/Kalah, before the contents. I'm copying them here.

The game provides a Kalah board and a number of seeds or counters. The board has 6 small pits, called houses, on each side; and a big pit, called an end zone, at each end. The object of the game is to capture more seeds than one's opponent.

1. At the beginning of the game, four seeds are placed in each house. This is the traditional method.
2. Each player controls the six houses and their seeds on the player's side of the board. The player's score is the number of seeds in the store to their right.
3. Players take turns sowing their seeds. On a turn, the player removes all seeds from one of the houses under their control. Moving counter-clockwise, the player drops one seed in each house in turn, including the player's own store but not their opponent's.
4. If the last sown seed lands in an empty house owned by the player, and the opposite house contains seeds, both the last seed and the opposite seeds are captured and placed into the player's store.
5. If the last sown seed lands in the player's store, the player gets an additional move. There is no limit on the number of moves a player can make in their turn.
6. When one player no longer has any seeds in any of their houses, the game ends. The other player moves all remaining seeds to their store, and the player with the most seeds in their store wins.
It is possible for the game to end in a draw.

You can use a database, but your submission still needs to be submitted as .class, .java, .scala or .jar (meaning you need to bundle the database). We are figuring out what a sensible limit on this would be. It will, of course, be less than any limit imposed by StudOn.

Hello Katja,

the Kalah homework is due tomorrow, right?
Is the limit still the same as the limit of StudOn (200 MB as far as I remember?).

Best regards, Marco and Tobias

Yes, 200MB is ok.

When and where will the tournament occur?

I'm currently running the tournament on a laptop. It's just past round 1 (3 houses) and halfway into round 2 (4 houses).  A few agents that either produced exceptions or made an excessive amount of illegal moves got disqualified.  I expect to get through all the rounds by Monday or so.  On Tuesday, during lecture, we'll run a mini tournament between the winners from this year and past years. I'll also ask the teams with agents that did best or something interesting to talk about it briefly.

Should I post the intermediate scores?

Yes please, we'd be interested in the scores.

Best regards :)

Most agents entered the first round. Possible reasons for not getting into the first round were not working with the framework (possibly with some minor fixes), me noticing that they simply duplicated the Random Player, or similar. In addition to the submitted agents, there were three random players (named somewhat predictably) and Dennis' agent Jazzpirate.

300    Prometheus
297    Kalahmari
282    DerGeisterPanzer
279    MohamedKalah
276    SchwanksAgent
264    Jazzpirate
252    awenga gscheida agent
246    Backblech
228    UberAgent
204    Jeshannes
165    GreedyAgent
165    KilalAgent
156    MiniMuskAgent
144    MyKalahRandomSolver
135    Oli
129    XXXKalaaaaahHuakbarXXX
129    JovialAgent
126    BeulahBot3
123    Fladni
120    Random2
102    Random1
99    Random3
99    Agent_of_ChJo
99    Jmi928A
99    Freedom4HK
99    CoHe
99    Tars
90    IsekaiTrash
66    SomeMinMaxAgent

The first round saw some exceptions (NullPointer by CoHeAgent, IllegalArgumentException by FladniAgent and a thread exception by LitzuckAgent) and illegal moves:

 329    CoHe
 320    Fladni
 134    Oli
 107    BeulahBot3
  80    IsekaiTrash
  29    XXXKalaaaaahHuakbarXXX
  18    MiniMuskAgent
  12    KilalAgent
   9    Prometheus
   2    SchwanksAgent

Agents that did not throw exceptions and had at most 100 illegal moves in total got into round 2.
