Temel fikirler

Olarak uzun yönlendirilmiş yolları ve döngüleri takribi , Bjorklund, Husfeldt ve Khanna, Bilgisayar Bilimleri Ders Notları (2004), 222-233, yazarlar seyrek genişletici uzun bir yol grafikler de aç gözlü arama ile bulunabilir öneriyoruz her birinde hangi seçer G '' deki en büyük alt-çizgiyi kapsayan yolun mevcut kuyruğunun komşusu, burada G ', geçerli yoldaki köşeleri silinen orijinal grafiktir. Bir grafiğin bir genişletici grafik olup olmadığını test etmenin iyi bir yolundan emin değilim, ancak kesinlikle seyrek bir grafikle uğraşıyoruz ve çekirdeği yaklaşık 20000 köşe olduğundan ve sadece 15'lik bir çapa sahip olduğundan iyi olmalı genişleme özellikleri. Bu yüzden bu açgözlü buluşsal yöntemi benimsiyorum.

Bir grafik Verilen G(V, E), kullandığımız her köşe erişilebilir kaç köşe bulabilirsiniz Floyd-Warshall içinde Theta(V^3)zaman ya kullanılarak Johnson'un algoritmasını içinde Theta(V^2 lg V + VE)zaman. Bununla birlikte, çok büyük bir şekilde güçlü bir bileşeni (SCC) olan bir grafikle uğraştığımızı biliyorum, bu yüzden farklı bir yaklaşım benimsiyorum. Tarjan'ın algoritmasını kullanarak SCC'leri tanımlarsak , sıkıştırılmış grafik için G_c(V_c, E_c)zaman içinde çok daha küçük olacak topolojik bir sıralama elde ederiz O(E). Yana G_cbir DAG, biz de Ulaşılabilirliği hesaplayabilir G_ciçinde O(V_c^2 + E_c)zaman. (Bu kullanılmasında 26-2,8 içinde ima olduğunu ben sonradan keşfettim CLR ).

Çalışma süresindeki baskın faktör olduğundan E, önekler / sonekler için kukla düğümler ekleyerek bunu optimize ederim. Yani biten sözcüklerden ziyade 151 * 64 = 9664 kenarları -res kelimelerle başlayan restorayon ben biten sözcüklerden 151 kenarları -res için # res # ve 64 kenarları # res # başlayan kelimeleri restorayon .

Ve son olarak, her bilgisayar eski bilgisayarımda yaklaşık 4 dakika sürdüğünden, sonuçları önceki uzun yollarla birleştirmeye çalışıyorum. Bu çok daha hızlı ve şu anki en iyi çözümümü ortaya çıkardı.

"Del" -> "ersatz's"( tam sıralı )

En uygun çözümü bulmaya çalışmak zaman içinde çok maliyetli oldu. Öyleyse neden rastgele örnekler seçmiyorsunuz, elimizden gelenin en iyisini umuyoruz ve en iyisini umuyoruz?

İlk olarak Hash, bu önekle başlayarak önekleri tam dünyalarla eşleştiren (örn. "the" => ["the", "them", "their", ...]) Oluşturulur . Sonra listedeki her kelime için yöntem sequenceçağrılır. Muhtemelen takip edebileceği kelimeleri alır, Hashbir örnek alır 100ve kendini tekrar tekrar çağırır. En uzun çekilir ve gururla görüntülenir. RNG ( Random::DEFAULT) tohumu ve dizinin uzunluğu da görüntülenir.

İyi bir sonuç almak için programı birkaç kez çalıştırmak zorunda kaldım. Bu özel sonuç tohumla elde edildi328678850348335483228838046308296635426328678850348335483228838046308296635426 .

Tam kaynak kodum yok. Farklı yaklaşımlar deniyordum. Ancak burada, aynı uzunlukta bir sıra oluşturabilmesi gereken bazı kod parçacıkları bulunmaktadır. Üzgünüm, çok güzel değil.

Kod (Python):

Öncelikle verilerin bir miktar önişlenmesi.

from collections import defaultdict

with open('words') as f:
    words = [line.strip() for line in f]
words = [word for word in words if len(word)>=3 and word[-2:]!="'s"]

word_connections = defaultdict(list)
for word in words:
    word_connections[word[:3]].append(word)

Sonra özyinelemeli bir işlev tanımladım (Derinlik ilk arama).

global m
m=0
def find_chain(chain):
    s = set(word_connections[chain[-1][-3:]])-set(chain)
    if len(s)== 0:
        global m
        if len(chain) > m:
            m=len(chain)
            print(len(chain), chain)
    else:
        for w in s:
            if w not in chain:
                find_chain(chain + [w])

for word in words:
    find_chain([word])

Tabii ki bu çok uzun sürüyor. Ama bir süre sonra 1090 elementli bir dizi buldu ve durdum.

Yapılacak bir sonraki şey, yerel bir aramadır. Sekanstaki her iki komşu n1, n2 için, n1'den başlayıp n2 ile biten bir sekans bulmaya çalışırım. Böyle bir dizi varsa, onu eklerim.

def tryimpove(chain, length, startvalue=0):
    s=set(chain)
    for i in range(startvalue,len(chain)-1):
        print(i)
        for sub in sorted(short_sequences([chain[i]],length,chain[i+1]),key=len,reverse=True):

            if len(s & set(sub))==1:
                chain[i:i+1]=sub
                print(i,'improved:',len(chain))
                return tryimpove(chain,length,i)
    return chain

def short_sequences(chain,length,end):
    if 2 <= len(chain):
        if chain[-1][-3:]==end[:3]:
            yield chain
    if len(chain) < length:
        s = set(word_connections[chain[-1][-3:]])-set(chain)
        for w in s:
            for i in short_sequences(chain + [w],length,end):
                yield i

for m in range(5, 100):
    seq = tryimpove(seq,m)

Tabii ki programı manuel olarak da durdurmak zorunda kaldım.

PHP, 1742 1795

Bu konuda PHP ile uğraşıyorum. Hile, listeyi gerçekten geçerli olan yaklaşık 20k'ye çıkarıyor ve geri kalanını atıyor. Programım bunu yinelemeli olarak yapıyor (bazı kelimeler ilk yinelemede atıyor, başkalarının artık geçerli olmadığı anlamına geliyor).

Kodum korkunç, bir dizi küresel değişken kullanıyor, çok fazla bellek kullanıyor (her önleme için tüm önek tablosunun bir kopyasını saklıyor) ve mevcut en iyi durumumu bulmak gerçekten günler sürdü, ancak yine de yönetiyor kazanmak için - şimdilik. Oldukça hızlı bir şekilde başlar, ancak zaman geçtikçe yavaşlar ve yavaşlar.

Düzenle küçük iyileştirme: Tüm kaldırarak uselessonların ekleri önek listesinde değilse, başında kelimeleri (Açıkçası son kelime olur)

Sonra listeden bir kelime alın ve önek haritasına bir ağaç düğümü gibi göz atın

Program durdurmak ne zaman bilmek için bir kaç kelime gerekir, olarak bulabilirsiniz 1733 , yöntemdecheckForNextWord̀

Program argüman olarak dosya yoluna ihtiyaç duyuyor

Çok pitonik değil ama denedim.

Öncelikle listeyi elle silerek

• büyük harf ile kelimeler
• kesme işareti olan kelimeler
• éêèáâàö ile kelimeler
• 1- ve 2 harfli kelimeler

bu kelimeler en fazla 2 puana mal oluyor, çünkü bu kelimeler sadece zincirin başında veya sonunda olabilir, ancak kelime listesini 1/3 oranında azaltır ve unicode ile uğraşmak zorunda değilim.

Sonra, ön ve son eklerin üst üste binme kümesinde olmadığı sürece tüm ön ve son eklerin bir listesini oluşturur, üst üste binmeyi bulur ve tüm kelimeleri atarım. Yine, bu maksimum ulaşılabilir puanımdan en fazla 2 puan alıyor, ancak kelime listesini orijinal boyutun üçte birine indiriyor (olası bir hızlanma için algoritmanızı kısa_listede çalıştırmayı deneyin ) ve kalan kelimeler yüksek oranda bağlı (bazıları 3 hariç) -sadece kendilerine bağlı olan kelimeler). Aslında, ortalama 4 kenarlı bir yoldan hemen hemen her kelimeye başka bir kelimeden ulaşılabilir.

Bağlantı sayısını, tüm işlemleri basitleştiren ve ileriye n adım atma ya da döngü sayma gibi havalı şeyler yapmama izin veren bir bitişiklik matrisinde saklıyorum ... en azından teoride, aslında yapmadığım matrisi karelemek yaklaşık 15 saniye sürüyor Bu arama sırasında. Bunun yerine rastgele bir önekle başlıyorum ve rastgele bir şekilde dolaşıyorum, ya eşit bir şekilde bir bitiş seçerek, sık sık meydana gelenleri ('-ing' gibi) ya da daha az meydana gelenleri tercih ediyorum.
Üç varyantın hepsi eşit derecede emer ve 20-40 aralığında zincirler üretir, ancak en azından hızlıdır. Sonuçta özyineleme eklemeliyim.

Başlangıçta ben benzer bir şey denemek istedim bu ama bu döngü ile yönlendirilmiş grafiktir beri, Topolojik Sorting, Uzun Yolun, büyük Euler Yol ya da Çinli Postacı Problemi iş için standart algoritmaları hiçbiri ağır değişiklik yapılmadan.

Ve sadece güzel göründüğü için, burada beyaz = sıfır girişleri olan M, M ^ 2 ve M ^ sonsuzluk matrisinin (sonsuzluk = 32, daha sonra değişmez) bir resmi var
