Python Sympy Permutation.unrank_trotterjohnson()用法及代碼示例


Permutation.unrank_trotterjohnson():unrank_trotterjohnson()是一個Sympy Python庫函數,可返回Trotter Johnson排列取消排序

用法: sympy.combinatorics.permutations.Permutation.unrank_trotterjohnson()

返回:Trotter Johnson排列置換


代碼1:unrank_trotterjohnson()示例

# Python code explaining 
# SymPy.Permutation.unrank_trotterjohnson() 
  
# importing SymPy libraries 
from sympy.combinatorics.partitions import Partition 
from sympy.combinatorics.permutations import Permutation 
  
# Using from sympy.combinatorics.permutations.Permutation.unrank_trotterjohnson() method  
  
# creating Permutation 
a = Permutation([[2, 0], [3, 1]]) 
  
b = Permutation([1, 3, 5, 4, 2, 0]) 
  
size = 3
  
rank = 5
  
print ("Permutation a - unrank_trotterjohnson form : ", a.unrank_trotterjohnson(size, rank)) 
print ("Permutation b - unrank_trotterjohnson form : ", b.unrank_trotterjohnson(5, rank))

輸出:

Permutation a – unrank_trotterjohnson form : (2)(0 1)
Permutation b – unrank_trotterjohnson form : (0 4 2 1)

代碼2:unrank_trotterjohnson()示例

# Python code explaining 
# SymPy.Permutation.unrank_trotterjohnson() 
  
# importing SymPy libraries 
from sympy.combinatorics.partitions import Partition 
from sympy.combinatorics.permutations import Permutation 
  
# Using from  
# sympy.combinatorics.permutations.Permutation.unrank_trotterjohnson() method  
  
# creating Permutation 
a = Permutation([[2, 4, 0],  
                 [3, 1, 2], 
                 [1, 5, 6]]) 
  
  
print ("Permutation a - unrank_trotterjohnson form : ", a.unrank_trotterjohnson(4, 8))

輸出:

Permutation a – unrank_trotterjohnson form : (3)(0 2 1)
