常見例句Here the changes lie in constantly trying out new wirings of the Enigma plugboard. 梯度算法逐步對對象(在此情況下為線路連接板設置)進行改變,以此來優(yōu)化對象。The program iterates through all possible machine settings except the plugboard settings. 程序重復通過所有可能的機器裝置,當然配線板裝置除外。This is a major shortcut since the plugboard settings form a huge portion of the key space. 這是一條重要的捷徑,通過設置線路連接板的步線來生成大量的密鑰空間。For each of these machine settings the program uses a hill climbing algorithm to find the optimal plugboard settings. 對這些機器中的每一臺都設置程序使用梯度算法(hillclimbingalgorithm,爬山法)來尋找最佳的線路連接板步線方式。Hill climbing algorithms try to optimize an object, in this case the plugboard settings, by changing the object step by step. 梯度算法逐步對對象(在此情況下為線路連接板設置)進行改變,以此來優(yōu)化對象。In their Cryptologia paper "Breaking German Army Ciphers" Geoff Sullivan and Frode Weierud show a very efficient way of rewiring the plugboard during the hill climb. 在由GeoffSullivan和FrodeWeierud合作完成的密碼術論文“BreakingGermanArmyCiphers”中給出了一種非常有效的方式在進行梯度算法處理過程中對線路連接板重新步線的方法。 返回 plugboard
