I would like some assistance correcting an issue I am having
with this assignment.
Once a finite state automaton (FSA) is designed, its transition
diagram can be translated in a straightforward manner into program
code. However, this translation process is considerably tedious if
the FSA is large and troublesome if the design is modified. The
reason is that the transition information and mechanism are
combined in the translation.
To do it differently, we can design a general data structure
such as a table or a list to hold the transition information, and
to implement in program code only a general transition mechanism.
Using this approach, the resulted program is not only smaller, but
it can also be modified easily to simulate a different FSA by just
changing the transition information and the general data structure
holds. We shall refer to such a program as a universal finite
state automaton.
Your job for this assignment is to implement such a universal
finite state automaton. To convince you that it is very easy to do
so, I have suggested an algorithm below; however, you are free to
modify it. Note that your program has to be designed to handle the
FSA where the input transition function is partial, which means
there is a default dead-end, or trap state.
1 state = initial_state; exit = false;
2 while not exit do
3 begin
4 symbol = getNextSymbol();
5 if symbol is in alphabet then begin
6 state = getNextState(state, symbol);
7 if state is dead_end then begin exit = true; reject; end
8 end
9 else begin
10 exit = true;
11 if symbol is not the endmarker then reject;
12 else if state is final then accept;
13 else reject;
14 end //if
15 end //while
The above algorithm shows how to process one input string and
correctly determine
whether the string is in the language. You need to augment the
algorithm so that your program is able to read in different FSA
descriptions from an input file and simulate one machine at a time
with any number of test strings.
You must represent each FSA in the input file with the following
format, and put all input machines in one file:
(1) The number of states, say N.

For ease of implementation, number states from 0 to N-1, with 0
representing the initial
state, and N the dead-end state.
(2) The set of final states.

You need a boolean array FINAL [0..N-1].
(3) The alphabet.

Symbols in the alphabet should be numbered internally so that the
value returned by the
function getNextSymbol is an integer.
(4) A sequence of transitions of the form (p a q).

The triple (p a q) means that in state p, looking at input symbol
a, the FSA will change
its state to q. For this project, store this information in a
table, say next_state, so that the value returned by the function
getNextState is next_state [state, symbol].
Test your program with the following 5 finite state automata
using the given test strings.
(1) A FSA which recognizes the set of all binary strings with at
most one pair of consecutive 0s and at most one pair of
consecutive 1s. Strings: _, 00, 0011, 110011,
010101, 000, 00102, 1100101, 10110100101, 1001011010110
(2) A FSA which recognizes email addresses. A valid email
address is defined as follows: [email protected],
where the user name consists of at least one symbol with any
combination of letters, digits, hyphens, underscores, or periods.
The server name is any string of at least one symbol with any
combination of letters, digits, hyphens, and underscores. The
domain name must have 2 to 4 letters. Strings:
[email protected], jsmith, [email protected], [email protected],
[email protected], jsmith.edu, [email protected],
[email protected], [email protected],
[email protected]
(3) A FSA which recognizes all identifiers that begin with a
letter (both upper and lower), an underscore, or a dollar sign,
followed by any combination of letters, digits, underscores, and
dollar signs. Strings: a, $, _, TAX_RATE, $amount,
week day, 3dGraph, X3y7, _finite_automaton, X*Y
(4) A FSA which recognizes the set of all signed or unsigned
decimal numbers without superfluous leading or trailing zeros. For
instance, 0.0, -0.5, +120.01, and 123000.0 are in the language, but
0.00, 00.5, and 0123.4 are not. Each decimal number has the form of
A.B, where A and B are strings of digits and they cannot be empty
at the same time. Strings: +1.23, -.123, 123.,
-0.0, 01234.5, +789, ., 56.30, +120.0001, 123000.0
(5) A FSA which recognizes the set of strings over {0, 1, 2}
such that the final digit has not appeared before.
Strings: 0, 01, 012, 22, 2102, 0221, 01012,
120120, 110221210, 0202321
Sample input of a FSA: 2


(0 0 0) (0 1 1) (1 0 1) (1 1 0) 1000 10001 ……..
Corresponding output:

Finite State Automaton #1.
(1) number of states: 2 (2) final states: 1

(3) alphabet: 0, 1

(4) transitions:
000 011 101 110
(5) strings: 1000 accept
10001 reject
here is current code, but doesn’t seem to be working properly.
Some strings that I should be accepting are being rejected
