Python SymPy Permutation.get_adjacency_distance()用法及代码示例

Permutation.get_adjacency_distance():get_adjacency_distance()是一个sympy Python库函数,用于计算两个置换之间的邻接距离。

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

返回:
两个置换之间的邻接距离


代码1:get_adjacency_distance()示例

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

输出:

a – get_adjacency_distance form b: 3
b – get_adjacency_distance form c: 5

代码2:get_adjacency_distance()示例– 2D排列

# Python code explaining 
# SymPy.Permutation.get_adjacency_distance() 
  
# importing SymPy libraries 
from sympy.combinatorics.partitions import Partition 
from sympy.combinatorics.permutations import Permutation 
  
# Using from  
# sympy.combinatorics.permutations.Permutation.get_adjacency_distance() method  
  
# creating Permutation 
a = Permutation([[2, 4, 0],  
                 [7, 1, 3], 
                 [8, 5, 6]]) 
  
b = Permutation([[8, 4, 0],  
                 [2, 7, 0], 
                 [1, 6, 7]]) 
      
print ("a get_adjacency_distance form b : ", a.get_adjacency_distance(b))

输出:

a get_adjacency_distance form b : 7
