检查算法时使用此输出。
Python代码:
import itertools
data = [
0.000000, #data[0]
0.000051, #data[1]
0.000076, #data[2]
0.000102, #data[3]
0.000152, #data[4]
0.000178, #data[5]
0.000203, #data[6]
0.000229, #data[7]
0.000254, #data[8]
0.000279, #data[9]
0.000305, #data[10]
0.000356, #data[11]
0.000381, #data[12]
0.000406 #data[13]
]
for j in sorted((abs(i[0][0]-i[1][0]), (i[0][1],i[1][1])) for i in itertools.combinations( zip(data,range(len(data))), 2)):
print str(j[1]).ljust(8), '->',j[0]#indices -> distance

所以最小的集合是(data[7],data[8])。
如果您在计算之前对数据进行排序,则从输出中,您可以轻松找到这样的最小距离。
#This is pseudocode.
x[n] = data[n] - data[n-1]
min(x)
