我遇到的一个问题是,给定二进制序列a_0,...,a_ {n-1}需要多少转换,以便当给定非负整数i时,如果i
使用https://martinugarte.com/turingmachine/我模拟了以下图灵机,试着了解应该采取多少个状态
n = 2,5转换的序列
//Sequence is 0,1
name: Sequence
init: one
accept: end
one,0
end,0,-
one,1
two,_,>
two,_
end,1,-
two,0
end,0,-
two,1
end,0,-
用n = 3,8个转换序列
//Sequence is 0,1,0
name: Sequence
init: one
accept: end
one,0
end,0,-
one,1
two,_,>
two,_
end,1,-
two,0
three,_,>
two,1
end,0,-
three,_
end,0,-
three,0
end,0,-
three,1
end,0,-
n = 4,11次转换的序列
//Sequence is 0,1,0,1
name: Sequence
init: one
accept: end
one,0
end,0,-
one,1
two,_,>
two,_
end,1,-
two,0
three0,_,>
two,1
three1,_,>
three0,_
end,0,-
three0,0
end,0,-
three0,1
end,0,-
three1,_
end,1,-
three1,0
end,0,-
three1,1
end,0,-
由此我猜测,指定序列n long需要大致O(n)个状态。你能证明这一点吗?
