Question

I built a Turing Machine in JFLAP is a binary adder. It is a 3 tape TM: first two tapes are inputs, and the 3rd tape gets the output. When I try to do the batch testing (info found here), I cannot get the 3rd string in my .txt file to become the output tape. My .txt file is built like:

00110 11100110 11001110 accept
10101 010 11101 accept 
111 1111 01101 accept
1010 101 0101 accept
0001 001001010101 001101010101 accept

However, because it is a 3 tape machine, and it must be, the last binary string that I want to be the output string is taken as the 3rd input string, which should be blank for all the tests. Is there any way I can format my test strings so JFLAP understands the last string should be the output?

Answer 1

I found that I needed to put an extra space after the first two inputs; thus, the 3rd input string would be an empty string. So the first line would be:

00110 11100110  11001110 accept
