SimpleTuringMachine是一个基于Python的实现，用于模拟图灵机的行为。它使用多磁带确定性图灵机（MDTM）来表示图灵机。MDTM是一种图灵机模型，其中每个状态都有一个对应的磁带，磁带上存储着该状态的信息。当输入一个字符时，机器从磁带中读取信息，并根据读取到的信息执行相应的操作。

在SimpleTuringMachine中，我们可以通过以下步骤实现MDTM：

1. 定义一个类，名为MDTM，继承自SimpleTuringMachine。
2. 在MDTM类中，定义一个方法，名为run，用于模拟图灵机的行为。
3. 在run方法中，首先创建一个空的字典，用于存储当前状态的信息。
4. 然后，根据输入的字符，从磁带中读取信息，并将其添加到字典中。
5. 根据读取到的信息，执行相应的操作。
6. 最后，将当前状态的信息保存到磁带中。

以下是一个简单的示例代码：

class MDTM(SimpleTuringMachine):

    def __init__(self, states, transitions):

        super().__init__(states, transitions)

        self.state_info = {}



    def run(self, input_char):

        # 从磁带中读取信息

        state_info = self.state_info.get(input_char)

        if not state_info:

            raise ValueError("Invalid input character")



        # 根据读取到的信息执行相应的操作

        if state_info == "A":

            self.state_info["B"] = "C"

        elif state_info == "B":

            self.state_info["C"] = "D"

        elif state_info == "C":

            self.state_info["D"] = "E"

        elif state_info == "D":

            self.state_info["E"] = "F"

        elif state_info == "E":

            self.state_info["F"] = "G"

        elif state_info == "F":

            self.state_info["G"] = "H"

        elif state_info == "G":

            self.state_info["H"] = "I"

        elif state_info == "H":

            self.state_info["I"] = "J"

        elif state_info == "I":

            self.state_info["J"] = "K"

        elif state_info == "J":

            self.state_info["K"] = "L"

        elif state_info == "K":

            self.state_info["L"] = "M"

        elif state_info == "L":

            self.state_info["M"] = "N"

        elif state_info == "M":

            self.state_info["N"] = "O"

        elif state_info == "N":

            self.state_info["O"] = "P"

        elif state_info == "O":

            self.state_info["P"] = "Q"

        elif state_info == "P":

            self.state_info["Q"] = "R"

        elif state_info == "Q":

            self.state_info["R"] = "S"

        elif state_info == "S":

            self.state_info["T"] = "U"

        elif state_info == "T":

            self.state_info["U"] = "V"

        elif state_info == "V":

            self.state_info["W"] = "X"

        elif state_info == "W":

            self.state_info["X"] = "Y"

        elif state_info == "X":

            self.state_info["Y"] = "Z"

        elif state_info == "Y":

            self.state_info["Z"] = "AA"

        elif state_info == "Z":

            self.state_info["AA"] = "BB"

这个示例代码实现了一个MDTM，它可以处理字符串"ABCDEFGHILMNOPQRSTUXYZ"。多磁带确定性图灵机c++实现
