Wprowadzenie

Gra toczy się w małym świecie z różnymi miastami. Władcy miast nienawidzą się nawzajem i chcieliby rządzić światem. Ludzie dzielą się na dwie grupy, wojowników i dzieci. Nisko urodzone dzieci mogą jednak wychowywać na wojowników. Jesteś władcą trzech z tych miast.

Rozgrywka

Na początku gry rządzisz trzema miastami. W każdym mieście jest 100 osób. Musisz podzielić je na rycerzy i nisko urodzonych.

Następnie rozpoczyna się faktyczna gra turowa. Tura wygląda następująco: "Produce" knights=> execute command of first town=> execute command of next town(powtórz dla wszystkich miast) => try a rebellion.

• W każdej turze twój program będzie wywoływany dla każdego miasta, które należy do ciebie . Możesz albo zaatakować miasto , wesprzeć miasto lub po prostu zaczekać . Działania te będą wykonywane sekwencyjnie, a nie jednocześnie.
• Co trzecią turę dostajesz jednego rycerza na 2 nisko urodzonych (23 nisko urodzonych => 11 rycerzy). Ilość nisko urodzonych dzieci pozostaje taka sama.
• Rycerze w mieście mają premię do obrony w wysokości 1,2. Jeśli zostaniesz zaatakowany, twoi rycerze zostaną pomnożeni przez tę liczbę (np. Masz 78 knights, będziesz miał 93 knightspodczas ataku). Po ataku dodatkowi rycerze zostaną usunięci (jeśli 82 knightsprzeżyjesz, nadal będziesz miał 78 knights).
• W ataku każdy rycerz zabija wroga przed śmiercią. Na przykład: 30 knightsatak 100 knights(bez premii do obrony) => 70 rycerzy przeżyje.
• Możesz przejąć miasto zabijając wszystkich znajdujących się w nim rycerzy . Wszyscy nisko urodzeni należą teraz do ciebie, a twoi ocalali rycerze stacjonują w mieście. W następnej rundzie możesz rządzić tym miastem oprócz wszystkich innych miast .
• Po zdobyciu miasta nie będzie miało bonusu do obrony przez 2 pełne tury (ponieważ bramy są zniszczone). W trzeciej turze bramy zostaną naprawione.
• Aby zapobiec buntowi nisko urodzonych, potrzebujesz co najmniej o połowę mniej rycerzy niż nisko urodzonych (23 nisko urodzonych w mieście potrzebuje co najmniej 12 rycerzy w tym samym mieście). W przeciwnym razie nisko urodzeni zabiją wszystkich rycerzy, a miasto stanie się „neutralne” (bez lidera wskazanego przez PlayerId -1).
• Neutralne miasta będą „produkować” rycerzy, ale nie będą atakować ani wspierać innych miast.

Składnia

Kontroler zapewnia dane wejściowe za pomocą argumentów poleceń, program musi wyświetlać dane wyjściowe za pomocą standardowego wyjścia.

Wyjście (przygotowanie)
Przed rozpoczęciem gry kontroler wzywa cię do poddania się bez argumentów. Oznacza to, że musisz rozdzielić swoje 100 osób (dla każdego miasta) na rycerzy i nisko urodzonych. Musisz KnightCount KnightCount KnightCountna przykład wysyłać dane wyjściowe 95 80 95.

Wejście
Round;YourPlayerId;YourTownId;PlayerId_TownId_knights_lowborns;PlayerId_TownId_knights_lowborns;...
W pierwszej rundzie będzie to coś w rodzaju 1;2;2;0_0_100_0;1_1_50_50;2_2_80_20. Tutaj widzisz, że jest to pierwsza runda, jesteś graczem 2 w mieście 2. Masz 80 rycerzy i 20 nisko urodzonych.

W dalszej części gry może to być coś w rodzaju 20;2;1;0_0_100_0;2_1_30_50;2_2_40_20. Nadal jesteś graczem 2 (to się nigdy nie zmienia), ale przejąłeś miasto 1 (które obecnie kontrolujesz).

Wyjście
A TownId NumberOfKnights lub S TownId NumberOfKnightslub W(do oczekiwania).
Przykład: A 2 100(atakuj miasto 2 100 rycerzami) lub S 3 2(wspieraj miasto 3 2 rycerzami).

Zasady

• Boty nie powinny być pisane w celu pokonania lub wspierania określonych innych botów.
• Zapis do plików jest dozwolony. Napisz do „ twojasubmissionname .txt”, folder zostanie opróżniony przed rozpoczęciem gry. Inne zasoby zewnętrzne są niedozwolone.
• Twoje zgłoszenie ma 1 sekundę na odpowiedź (na miasto).
• Podaj polecenia, aby skompilować i uruchomić swoje zgłoszenia.

Zwycięski

Zwycięzcą jest ten, który ma najwięcej miast po 100 rundach. Jeśli gracz przejmie wszystkie miasta, gra się kończy i wygrywa. Jeśli wielu graczy ma taką samą liczbę miast, liczą się rycerze, a następnie liczba nisko urodzonych.

Kontroler

Kontroler można znaleźć na github. Zawiera także 2 sampleboty napisane w Javie. Otwórz go w Eclipse, umieść skompilowane boty w folderze głównym i dodaj klasę do programu sterującego (podobnie jak sampleboty).

Wyniki

Python 2, The King

Król rządzi miastem o najwyższej liczbie w swoim imperium i żąda wysłania nadmiaru rycerzy z innych miast pod jego kontrolą. Gdy będzie miał dość rycerzy, zaatakuje miasto wroga. Nie jest bardzo mądrym Królem, więc nie studiował historii ani nie rozumie konsekwencji swoich działań.

Java, Frankenstein

Próbując znaleźć sposób na zniszczenie Liberatora, w moim kodzie wpadł mały błąd. Kod zaczął wtedy niszczyć konkurencję. Po dodaniu Demokracji i uporządkowaniu graczy zaczęło się to nie udać. Studiując kod, próbowałem znaleźć jego strategię. W związku z tym utworzono następujący kod. Ma tendencję do atakowania i niszczenia najlepszego gracza. Po zniszczeniu najlepszych graczy, łatwo to niszczy resztę.

C ++ 11, CalculatedFail

po tym, jak wypróbowałem kilka rzeczy z małą Javą, którą znam i nie byłem w stanie osiągnąć tego, czego chciałem, postanowiłem napisać ją ponownie w C ++ i dodać obsługę plików. Problem polegał na tym, że mój C ++ jest dość zardzewiały i niewiele lepszy, więc niektóre części są ze sobą powiązane i to tylko pierwsze rozwiązanie w Google, więc nie bardzo dobry kod ...

mimo to udało mi się uzyskać przynajmniej działający wynik, który nie jest do kitu, wygrywa przynajmniej czasami, ale nie mogę go idealnie przetestować, ponieważ nie jestem w stanie uruchomić wszystkich innych zgłoszeń na tym komputerze. Prawdopodobnie przepiszę całkowicie kierowanie i dodam je jako kolejną odpowiedź dzisiaj lub jutro.

Google mówi na Linuksie, że to CalculatedFail.out zamiast .exe, ale nie mogę go przetestować.

i biegnij CalculatedFail.exe

ponieważ używa pliku do sprawdzenia premii def, jednoczesne uruchomienie gry wiele razy może prowadzić do błędów ...
