Python 中的 SymPy | arrange.min()

原文:https://www.geesforgeks.org/sympy-置换-min-in-python/

replacement.min():min()是一个 sympy Python 库函数，返回置换中的最小值。

语法:sympy.combinations .排列. arrange.min()

返回:排列中的最小值

代码#1 : min()示例

# Python code explaining
# SymPy.Permutation.min()

# importing SymPy libraries
from sympy.combinatorics.partitions import Partition
from sympy.combinatorics.permutations import Permutation

# Using from sympy.combinatorics.permutations.Permutation.min() method 

# creating Permutation
a = Permutation([[2, 0], [3, 1]])

b = Permutation([1, 3, 5, 4, 2, 0])

print ("Permutation a - min form : ", a.min())
print ("Permutation b - min form : ", b.min())

输出:

排列 a–最小形式:0 排列 b–最小形式:0

代码#2 : min()示例–2D 置换

# Python code explaining
# SymPy.Permutation.min()

# importing SymPy libraries
from sympy.combinatorics.partitions import Partition
from sympy.combinatorics.permutations import Permutation

# Using from sympy.combinatorics.permutations.Permutation.min() method 

# creating Permutation
a = Permutation([[2, 4, 0], 
                 [3, 1, 2],
                 [1, 5, 6]])

print ("Permutation a - min form : ", a.min())

输出:

排列 a–最小形式:0
