Kontes telah berakhir. Pengecut adalah pemenangnya. Anda dapat menonton pertandingan terakhir di sini .

Tiba-tiba zombie muncul! OH TIDAK!

Dalam tantangan king-of-the-hill ini, Anda harus membuat bot untuk selamat dari kiamat zombie. Atau setidaknya, bertahan selama mungkin.

Pada awal permainan, 50 instance dari setiap entri akan ditempatkan secara acak di area bermain toroidal besar - yaitu, tampaknya persegi, tetapi membungkus. Ukuran area bermain akan bervariasi tergantung pada jumlah entri, tetapi awalnya 6% kotak akan ditempati. Setiap pesaing dimulai dengan 3 peluru.

Di awal setiap belokan, zombie akan bangkit dari tanah di lokasi acak, menghancurkan apa pun yang ada di atasnya. Setiap pemain yang berada di sebelah zombie pada awal giliran mereka akan menjadi zombie.

Untuk setiap pemain yang masih hidup, kode mereka kemudian akan dipanggil. Ini akan menerima objek PlayerContext , berisi informasi tentang status mereka saat ini, dan lingkungan mereka. Setiap pemain dapat melihat 8 kotak di segala arah.

Pemain harus memilih untuk bergerak (tetap diam adalah gerakan yang valid), dengan mengembalikan Move, atau menembak orang atau zombie di dekatnya, dengan mengembalikan a Shoot. Pistol Anda memiliki jangkauan maksimum 5 kotak. Karena Anda berada dalam jangkauan senjata Anda, Anda dapat menembak diri sendiri, asalkan Anda memiliki peluru tersisa. Jika dua pemain saling menembak, mereka berdua mati.

Jika dua pemain mencoba untuk pindah ke kotak yang sama, mereka akan gagal, dan keduanya akan kembali ke kotak mereka mulai. Jika masih ada konflik, ini akan diulangi sampai tidak ada konflik, yang mungkin berarti semua orang kembali ke tempat mereka memulai.

Jika seorang pemain meninggal karena tembakan, mayat mereka akan tetap, dan membentuk penghalang permanen. Peluru apa pun yang mereka bawa tetap pada orang mereka, dan dapat diambil oleh pemain di kotak yang berdekatan. Jika ada beberapa pemain yang menempati kotak yang berdekatan dengan mayat, maka peluru akan dibagikan di antara mereka, tetapi sisanya akan hilang.

Jika seorang pemain menjadi zombie, maka peluru mereka hilang. Zombies akan berjalan tanpa berpikir menuju pemain yang hidup terdekat.

Entri diberi skor tentang berapa lama pemain mereka yang bertahan paling lama bertahan.

Entri

Program kontrol tersedia di https://github.com/jamespic/zombies . Cukup mengkloningnya, dan jalankan mvn compile exec:java.

Agar memenuhi syarat, entri harus ditulis dalam bahasa JVM, harus portabel, dan harus memungkinkan untuk dibuat dari Maven tanpa pengaturan khusus. Ini untuk memastikan bahwa pesaing tidak perlu menginstal beberapa lingkungan run-time untuk menguji bot mereka terhadap pesaing.

Entri sampel saat ini tersedia dalam bahasa berikut:

• Java 7 - lihat juga contoh yang lebih kompleks , dan kode untuk zombie
• Scala 2.11.1
• Javascript (via Badak)
• Python (via Jython 2.7 beta 2)
• Ruby (via JRuby 1.7.13)
• Clojure 1.5.1
• Frege (sedikit seperti Haskell - inilah contoh lain )

Jika Anda ingin bersaing dalam bahasa yang tidak terdaftar, Anda dapat memposting komentar yang memintanya, dan saya akan menyelidiki kemungkinan mengintegrasikan bahasa yang Anda pilih ke dalam program kontrol. Atau, jika Anda tidak sabar, Anda dapat mengirimkan permintaan tarik ke program kontrol.

Hanya satu contoh (dalam arti kata Jawa) yang akan dibuat untuk setiap entri. Mesin virtual Java ini akan dipanggil beberapa kali per giliran - satu kali untuk setiap pemain yang masih hidup.

API

package zombie

// You implement this. Your entry should be in package `player`
interface Player {
    Action doTurn(PlayerContext context)
}

// These already exist
class PlayerContext {
    // A square array, showing the area around you, with you at the centre
    // playFields is indexed by x from West to East, then y from North to South
    PlayerId[][] getPlayField()
    int getBullets() // Current bullets available
    int getGameClock() // Current turn number
    PlayerId getId() // Id of the current player instance
    int getX() // Your current x co-ordinate
    int getY() // Your current y co-ordinate
    int getBoardSize() // The size of the current playing field
    Set<PlayerId> shootablePlayers() // A helper function that identifies players in range.
}

class PlayerId {
    String getName() // The name of the entrant that owns this player
    int getNumber() // A unique number, assigned to this player
}

// Don't implement this. Use either `Move` or `Shoot`
interface Action {}

enum Move implements Action {
    NORTHWEST, NORTH, NORTHEAST,
    EAST, STAY, WEST,
    SOUTHEAST, SOUTH, SOUTHWEST;
    static move randomMove();
}

class Shoot implements Action {
    Shoot(PlayerId target);
}

Aturan tambahan

Setiap entri harus memiliki nama unik, agar dapat bekerja dengan benar dengan program kontrol.

Entri tidak boleh mencoba untuk mengutak-atik pendatang lain, atau dengan program kontrol, atau mengambil keuntungan dari lingkungan run-time untuk "memecahkan dinding keempat", dan mendapatkan keuntungan yang tidak akan tersedia dalam kiamat zombie "nyata" .

Komunikasi antar pemain diperbolehkan.

Pemenangnya adalah peserta yang botnya memiliki skor tertinggi dalam tes yang akan saya jalankan pada 3 Agustus 2014.

Hasil akhir

Hasil akhirnya ada di! Pengecut adalah pemenangnya!

Pada tanggal 2 Agustus, saya menjalankan 19 putaran program kontrol, dan memberi peringkat setiap pemain sesuai dengan skor median mereka. Hasilnya adalah sebagai berikut:

Pengecut

Aturan pengecut.

1. Jika Anda tidak bisa lari, panik dan tembak semua yang tidak Anda ketahui.
2. Lari!!!
3. Saat berlari, Anda mungkin juga mengambil beberapa peluru. Jauh di lubuk hati Anda tahu Anda tidak bisa lari selamanya.
4. Saat berlari, cari pengecut lainnya. Penderitaan mencintai perusahaan. Dan mereka mungkin makan orang lain dulu.

HuddleWolf - Jawa

Aturan 8 : Bepergian dalam Grup

HuddleWolf mengambil aturan keenam Zombieland ke dalam hati. Ini akan mengejar dan berkerumun dengan objek non-bermusuhan yang dilihatnya. Jika HuddleWolf melihat tidak ada orang yang berimpit, dia akan menjelajah timur laut untuk mencari daerah yang lebih padat. HuddleWolf juga membenci Zombies dan akan menembak pada pandangan.

HuddleWolf menyadari bahwa Coward adalah implementasi yang jauh lebih baik dari ide aslinya. Dia tunduk pada supremasi Coward dan sekarang secara aktif lebih suka ditemani oleh para pengecut daripada yang bukan tuan rumah.

Waller - Jawa

Waller menyukai dinding, dan mencari mereka untuk bersembunyi dari zombie. Idealnya, Waller akan senang terbungkus dalam dinding dan menunggu kiamat keluar.

Dinding Yang Ideal

Dinding yang ideal adalah tempat Waller diselesaikan dikelilingi oleh dinding:

   DDD 
   DWD 
   DDD

Sebagai satu-satunya cara untuk mati adalah untuk ditembak atau zombie menumbuhkan di bawah atau tetangga Anda. Ini adalah peluang terbaik untuk menghindarinya.

Dinding yang ideal sulit didapat, tetapi Waller akan menemukan lokasi terbaik dan menunggu zombie atau pemain lain datang kepadanya untuk menembak dan memperluas dindingnya.

Algoritma ini relatif sederhana

1. Apakah ada zombie yang akan digigit? tembak mereka.
2. Temukan lokasi dinding terbaik (skor 0 - 8) di bidang tampilan
3. Temukan jalur terpendek ke lokasi itu dan lari ke sana!
4. Coba tambah tembok
5. Tunggu...

Ini adalah pekerjaan yang sedang berjalan, jangan ragu untuk mengambil apa pun yang saya tulis untuk digunakan sendiri. Saya menulis Algoritma A * sederhana untuk menemukan jalan terbaik ke tempat yang diinginkan dengan mempertimbangkan dinding pertimbangan dan pemain lain. Itu akan dihitung ulang setiap putaran karena dinding mungkin telah berubah di antara mereka.

Changelog:

• Mencoba untuk meningkatkan kinerja permainan awal dengan menunggu dan menghindari pemain agresif untuk beberapa belokan pertama sebelum menemukan / membangun tembok.

• Penambahan bobot pada temuan path untuk mengambil rute terbaik dalam hal jarak dan skor posisi. Akan menjarah lebih sering sekarang dan semoga tidak kehabisan peluru. Permainan pembuka yang ditingkatkan dengan melarikan diri dari pemain agresif.

• Memperbaiki masalah dengan pencarian jalur yang berakhir pada titik yang diduduki

• Kode dibersihkan lebih lanjut. Menambahkan lebih banyak dinding untuk mencetak posisi daripada hanya dinding tetangga. Memperluas seberapa jauh Waller akan memperpanjang dindingnya.

• Kode dibersihkan sedikit. Registri pemotretan yang diimplementasikan untuk menghindari dua Wallers menembak pemain yang sama selama belokan yang sama (terinspirasi oleh Thaylon)

• Menambahkan pencarian jalur antara zombie terdekat dan Walelr saat ini. Waller hanya akan menembak zombie jika dapat menghubunginya dalam sejumlah gerakan tertentu. Mudah-mudahan ini akan menghemat beberapa peluru ketika itu adalah dinding yang menghalangi jalan zombie.

Masalah

• Waller mungkin dalam posisi yang baik, tetapi melihat lokasi dinding yang lebih baik. Mereka akan tanpa pikir panjang berlari melalui tanah yang dipenuhi zombie untuk mencapai lokasi baru itu. (Saya harus mencegah ini)

• Game awal sulit untuk Waller, tidak ada benteng yang baik di dekatnya dan banyak pemain agresif. (Saya perlu meningkatkan kinerja game awal)

• Tidak ada komunikasi antara Waller di lokasi yang sama. Perlu mereka bekerja sama untuk membangun tembok terbaik.

Ini kodenya, saya bukan programmer java (C #) jadi maafkan kesalahan java saya.
