Risiko, Jalan Warlight

12

pengantar

Dalam game ini, pemain menggunakan pasukan mereka untuk melawan tentara pemain lain, merebut wilayah, dan menjadi orang terakhir yang bertahan. Setiap belokan, pemain menerima jumlah pasukan dasar untuk digunakan sesuai keinginan mereka. Namun, dengan merebut wilayah di wilayah tertentu, pemain dapat meningkatkan jumlah ini untuk memberi mereka potensi keuntungan di kemudian hari dalam permainan. (Ini pada dasarnya sama dengan Warlight ).

Semua bot harus ditulis dalam Java, C, atau C ++ (saya akan menyertakan bahasa lain tetapi tidak memiliki perangkat lunak atau pengalaman untuk mereka). Pengajuan Anda tidak perlu untuk memperluas kelas, dan Anda dapat membuat fungsi, kelas, antarmuka, atau apa pun yang diperlukan, dan menggunakan paket atau kelas apa pun di API standar . Jika Anda berencana membuat kelas atau antarmuka, harap pertimbangkan untuk menggunakan kelas dalam atau antarmuka bagian dalam.

Tolong jangan mencoba untuk secara terprogram mengubah controller atau kiriman lainnya dalam kompetisi ini.

Gameplay

Gambaran

Array dua dimensi 10x10 akan mensimulasikan papan, setiap elemen / sel mewakili "wilayah". Akan ada 20 putaran dan hingga 1000 putaran per putaran. Setiap belokan, pemain pertama-tama akan mengerahkan pasukan yang mereka miliki ke salah satu wilayah yang mereka miliki, dan kemudian diberi kesempatan untuk mengangkut tentara mereka ke wilayah terdekat dalam upaya untuk menangkap wilayah lawan mereka dengan menyerang pasukan di dalamnya. Pemain harus mengerahkan semua pasukan mereka, tetapi mereka tidak harus memindahkannya jika diinginkan.

Serang / Pindahkan pasukan

Jika pemain menginginkan, ia dapat mengirim pasukan dari satu wilayah ke salah satu dari delapan wilayah yang berdekatan. Papan "membungkus", yaitu jika wilayah pemain di satu sisi, pasukan dari sana dapat ditransfer ke wilayah yang berdekatan di sisi lain. Ketika memindahkan pasukan dari suatu wilayah, seharusnya masih ada setidaknya satu pasukan tersisa di wilayah itu. Misalnya, jika suatu wilayah mengandung lima pasukan, tidak lebih dari empat pasukan dapat dipindahkan ke wilayah yang berbeda; jika suatu wilayah berisi satu, pasukan itu tidak bisa bergerak.

Jika seorang pemain mengirimkan npasukan dari satu wilayah ke wilayah yang mereka miliki, wilayah itu akan menerima npasukan.

Katakanlah seorang pemain mengirimkan npasukan dari wilayahnya ke wilayah lawan dengan opasukan di dalamnya. oakan berkurang secara n * .6bulat ke bilangan bulat terdekat; Namun, pada saat yang sama, nakan menurun secara o * .7bulat ke bilangan bulat terdekat. Aturan berikut yang berhubungan dengan apakah atau tidak wilayah yang ditawan telah ditangkap akan berlaku:

  • Jika omencapai nol DAN nlebih besar dari 0, pemain akan mengambil alih wilayah, yang akan memiliki npasukan di dalamnya.
  • Jika keduanya ndan omenjadi nol, osecara otomatis akan diatur ke 1 dan wilayah tidak akan ditangkap.
  • Jika otetap lebih besar dari 0, jumlah pasukan di wilayah pemain akan meningkat sebanyak ndan wilayah lawan tidak akan ditangkap.

Bonus

Sekelompok wilayah akan dipilih untuk mewakili bonus; jika satu pemain memiliki semua wilayah yang merupakan bagian dari grup, pemain itu akan menerima jumlah pasukan tambahan per giliran.

Bonus memiliki nomor id untuk menunjukkan nilai dan nilai yang berbeda yang mewakili jumlah pasukan tambahan yang dapat diterima pemain. Setiap putaran, nilai bonus akan menjadi angka acak antara 5 dan 10, inklusif, dan sepuluh bonus akan tersedia di lapangan, masing-masing dengan sepuluh wilayah termasuk dalam bonus.

Misalnya, jika pemain yang menerima 5 pasukan per giliran memiliki semua wilayah yang menghasilkan bonus dengan nilai 8, pemain akan menerima 13 pasukan pada giliran berikutnya dan putaran berikutnya. Namun, jika pemain kehilangan satu atau lebih wilayah yang membentuk bonus, ia akan menerima hanya 5 pasukan per giliran.

Input output

Program Anda harus mengambil input melalui argumen baris perintah, yang akan memiliki format berikut:

[id] [armies] [territories (yours and all adjacent ones)] [bonuses] ["X" (if first turn)]
  • iddan armieskeduanya bilangan bulat. idadalah id Anda, dan armiesmerupakan jumlah pasukan yang Anda perlu gunakan untuk wilayah Anda. Anda harus mengerahkan semua pasukan yang diberikan kepada Anda - tidak lebih dan tidak kurang.
  • territoriesadalah serangkaian string yang mewakili wilayah yang Anda miliki dan wilayah yang tidak Anda miliki yang berdekatan dengan wilayah Anda. String dalam format ini:

    [row],[col],[bonus id],[player id],[armies]
    

    rowdan colmenunjukkan baris dan kolom papan di mana wilayah itu, bonus idadalah id dari bonus bahwa wilayah ini adalah bagian dari, player idadalah id dari pemain yang memiliki wilayah itu, dan armiesadalah jumlah tentara yang terkandung di wilayah itu. Ini semua angka.

  • bonusesadalah serangkaian string yang mewakili bonus di papan yang dapat Anda manfaatkan. String dalam format ini:

    [id],[armies],[territories left]
    

    idadalah id dari bonus, armiesadalah jumlah pasukan tambahan yang dapat Anda terima dengan memiliki semua wilayah dalam bonus ini, dan territories leftjumlah wilayah dalam bonus yang perlu Anda tangkap untuk menerima pasukan tambahan.

Harap perhatikan bahwa argumen kelima, "X", akan muncul jika ini adalah putaran pertama putaran dan dapat digunakan untuk alasan kenyamanan.

Contoh input pada belokan pertama:

0 5 "7,6,7,-1,2 8,7,7,-1,2 7,7,7,0,5 6,6,7,-1,2 8,8,9,-1,2 6,7,7,-1,2 7,8,9,-1,2 6,8,9,-1,2 8,6,7,-1,2" "0,5,10 1,5,10 2,9,10 3,9,10 4,9,10 5,5,10 6,5,10 7,6,9 8,7,10 9,7,10" X

Program Anda harus menampilkan dua string yang dipisahkan oleh baris baru, yang pertama berisi daftar baris dan kolom wilayah yang ingin Anda tambahkan pasukannya dan jumlah pasukan yang ingin Anda tambahkan ke dalamnya, dan yang kedua mencantumkan baris dan kolom wilayah yang ingin Anda kirimi pasukan dan jumlah pasukan yang ingin Anda kirim. Output mungkin berisi spasi tambahan.

Untuk menentukan wilayah yang ingin Anda tambahkan pasukan, output Anda harus mengikuti format ini:

[row],[col],[armies]

rowdan coladalah baris dan kolom papan di mana wilayah yang ingin Anda tambahkan pasukan, dan armiesjumlah pasukan yang ingin Anda tambahkan ke wilayah tersebut.

Untuk menentukan wilayah yang ingin Anda kirimi pasukan, output Anda harus mengikuti format ini:

[srow],[scol],[drow],[dcol],[armies]

srowdan scoladalah baris dan kolom papan di mana wilayah tujuan pengiriman pasukan, drowdan dcolbaris dan kolom papan tempat tujuan pengiriman pasukan, dan armiesjumlah pasukan yang ingin Anda kirimi . Perhatikan bahwa jika Anda tidak ingin memindahkan pasukan apa pun, program Anda harus mencetak spasi.

Output sampel mungkin ini:

0,0,5
0,0,0,1,3 0,0,1,0,3 0,0,1,1,3

Dalam hal ini, pemain menyebarkan lima pasukan ke wilayah dengan 0,0 dan memindahkan tiga pasukan dari 0,0 ke 0,1; tiga dari 0,0 menjadi 1,0; dan tiga dari 0,01 ke 1,1.

Putaran dan Putaran

Pada awal setiap putaran, semua pemain akan diberikan satu wilayah yang terletak di tempat acak di papan (dimungkinkan bagi dua atau lebih pemain untuk mulai bersebelahan). Wilayah yang membentuk bonus juga dapat berubah.

Pada belokan pertama, setiap pemain akan memiliki satu wilayah yang berisi lima pasukan, dan mereka akan menerima lima pasukan yang dapat mereka gunakan (ini adalah minimum yang dapat mereka terima). Semua wilayah lain akan dimiliki oleh NPC yang tidak menyerang; masing-masing berisi dua pasukan dan memiliki id -1.

Setiap belokan program Anda akan dijalankan, dan kedua bagian output akan dikumpulkan. Pengontrol akan menerapkan bagian pertama dari output, segera menambahkan pasukan ke wilayah; namun, controller akan menunggu sampai semua pemain memberikan output kedua, perintah serangan / transfer mereka. Setelah ini selesai, perintah akan dikocok secara acak dan kemudian dieksekusi. Program Anda harus memberikan hasil dan berhenti dalam satu detik atau kurang untuk berpartisipasi dalam belokan.

Mencetak dan Menang

Untuk setiap putaran tertentu, jika satu pemain tetap, pemain itu akan mendapatkan 100 poin. Jika tidak, jika 1000 putaran berlalu dan masih ada beberapa pemain, 100 poin akan dibagi secara merata antara pemain yang tersisa (yaitu 3 pemain yang tersisa menghasilkan 33 poin masing-masing). Pemain mana pun yang memiliki poin terbanyak di akhir 20 putaran akan menang.

Pengajuan

Posting Anda harus menyertakan nama bot, bahasa tempat penulisan, deskripsi singkatnya, dan kode yang digunakan untuk menjalankannya. Contoh bot akan diposting di sini sebagai contoh dan akan digunakan dalam kontes. Anda dapat mengirimkan sebanyak yang Anda inginkan.

Lain

Program Anda dapat membuat, menulis, dan membaca dari suatu file selama nama file itu sama dengan nama yang Anda gunakan untuk pengiriman Anda. File-file ini akan dihapus sebelum awal turnamen tetapi tidak di antara putaran.

Giliran Anda akan dilewati jika:

  • Anda dihilangkan (tidak memiliki wilayah);
  • program Anda tidak mencetak apa pun;
  • program Anda tidak berakhir dalam satu detik;
  • Anda mengerahkan terlalu sedikit pasukan ke wilayah Anda (mengerahkan pasukan ke wilayah yang tidak Anda miliki akan diperhitungkan dalam hal ini) atau terlalu banyak pasukan; atau
  • output Anda menyebabkan controller melempar pengecualian.

Perintah serangan / transfer Anda tidak akan dieksekusi jika:

  • program Anda tidak memberikan hasil yang benar;
  • Anda memilih wilayah untuk memindahkan tentara dari yang bukan milik Anda;
  • Anda bergerak nol atau jumlah pasukan yang negatif dari wilayah Anda;
  • Anda memindahkan terlalu banyak pasukan dari wilayah Anda; atau
  • Anda memilih wilayah untuk mengirim pasukan yang tidak berdekatan dengan wilayah yang Anda pilih untuk memindahkan pasukan.

Anda dapat menemukan pengontrol dan bot sampel di sini . Bot akan berpartisipasi dalam permainan, tetapi mungkin tidak akan memenangkan putaran apa pun (kecuali jika benar - benar beruntung).

Hasil

Menjalankan pengontrol setelah mendorong perbaikan bug ke sana, WeSwarm terus menjadi kekuatan yang harus diperhitungkan. Dibutuhkan bot dengan strategi hebat untuk memiliki peluang melawannya.

JavaScript? Itu dapat dijalankan di konsol browser apa pun
Downgoat
Maaf tapi tidak; Saya ingin kiriman dalam salah satu dari tiga bahasa di atas.
TNT
Tidak yakin apakah itu bug di controller Anda atau bot pemain Anda, tetapi jika saya menempatkan tiga instance bot Anda dalam simulasi sendiri, konsol output: Perintah tidak valid oleh java Player: tidak ada output
Moogie
@ Moogie Apakah ini terjadi untuk setiap bot? Apakah itu dihasilkan secara konsisten (setiap belokan) atau secara berkala (setiap beberapa putaran)? Dan apakah Anda menggunakan "java Player" dalam array tiga kali atau apakah Anda membuat kelas terpisah?
TNT
@TNT ok itu masalah saya ... kita sebenarnya masalah IDE: P mengubah perintah menjadi "java -cp bin Player" dan semuanya baik-baik saja. maaf untuk itu.

Castler - Java 8

Dia hanya ingin membuat kastil persegi ... dan jika dibiarkan sendiri akan melakukan hal itu. Meskipun dia bosan dengan kastil kecil sehingga membuatnya semakin besar. Ini pasti akan berarti konflik dengan pemain lain dan pertempuran pun terjadi. Namun dia tidak pernah melupakan bentuknya yang paling diinginkan ... kotak.

Hermit - Jawa

Terus tambahkan pasukannya ke kota yang sama. Saya tidak berpikir itu bisa diturunkan tanpa mendapat bonus tentara.

public class Hermit {
    public static void main(String[] args) {
        int myId = Integer.parseInt(args[0]);

        for (String s : args[2].split(" ")) {
            String[] data = s.split(",");
            int id = Integer.parseInt(data[3]);
            int row = Integer.parseInt(data[0]);
            int col = Integer.parseInt(data[1]);

            if (id == myId) {

WeSwarm - C ++ 11 [v2.2]

Diperbarui ke v2.2 pada 25 Agustus 2015.

v2.2 - disesuaikan karena perubahan cara controller melaporkan pasukan.

v2.1 - TNT kesulitan menyusun kode saya, jadi saya berhenti menggunakan stoi.

v2.0 - refactor kode bersama dengan beberapa perbaikan bug.

Terima kasih! Sayangnya saya tidak dapat mengkompilasi program Anda karena stoitidak terselesaikan meskipun memiliki C ++ 11. Ada konsisten masalah dengan menyelesaikan itu yang saya belum mengetahui bagaimana melakukannya, jadi bisa Anda memberikan solusi alternatif yang tidak menggunakan stoi?
TNT
@TNT Ahh itu menyebalkan. Saya masih baru di C ++, tapi saya yakin saya bisa memikirkan sesuatu.
Zsw
@TNT Silakan lihat apakah Anda dapat mengompilasinya sekarang.
Zsw
Ini mengkompilasi dan berjalan dengan baik. Terima kasih!

Saya telah menambahkan koreksi ke bot Anda untuk melindungi terhadap indeks di luar batas. Silakan menerima atau mengabaikan koreksi
Moogie
Hei, terima kasih atas perhatiannya, tetapi dalam pengujian saya menjadi masalah. Anda tidak boleh null, karena satu-satunya wilayah yang dilewati adalah yang bersebelahan dengan yang saya miliki, sehingga setiap wilayah musuh memiliki setidaknya satu tetangga di myTerritories.

Gigih! Bot Anda dapat pulih dari kehilangan wilayah dengan mahir. kerja bagus.

Random Halver - Java 8

Bot yang sangat sederhana yang hanya memindahkan setengah pasukannya di setiap wilayah ke wilayah tetangga yang acak. Tidak masalah jika tetangga itu teman atau musuh ...

Meskipun tidak dapat bersaing dengan Castler, itu mengejutkan baik terhadap Player dan bot lainnya.
