Description: 把NFA确定化为DFA 的算法，实现将给定的NFA M，确定化为DFA M’，然后将DFA M状态最少化，将给定的DFA M的有限状态集S划分成若干互不相交的子集，使得：任何不同的两个子集中的状态都是可区别的，而同一子集中的任何两个状态都是等价的（要利用Ia函数，但并不需要构造ε-CLOSURE函数，因这是DFA）。输出化简后的DFA M’。
-NFA into a DFA to determine the algorithm to achieve a given NFA M, to determine into a DFA M ' , then the DFA M state minimization, given DFA M of finite state set S is divided into several disjoint subset, such that: any two different subset of the state are distinguishable, and the same subset of any two states are equivalent (to take advantage of Ia function, but does not need to construct ε-CLOSURE function, because This is a DFA). Output of the simplified DFA M ' . Platform: |

Description: Theory:
NDFA: It is a mathematical model containing 5 tuples
a) Q- finite non empty set elements of which are called as state.
b) T- set of alphabets.
c) δ- is a mapping function Q*{T {λ}}*2Q
d) S-start state i.e. S ε Q
e) F- F (subset) Q and F is a final state.
DFA: A finite automata is called DFA if
a) There is no transition for function λ.
b) For each state S and a input symbol ‘a’, there is at most one edge with a symbol ‘a’ leaving from S.
Algorithm:
1. Convert the given NDFA into state transition table where each state corresponds to a row and each input symbol corresponds to a column.
2. Construct the successor table(ST) which lists subset of state reachable from set of initial state
3. The transition graph given by the ST in the required DFA if possible reduces the number of state.
Eg:
NFA:
δ a b
qo q1 q2
q1 - q0
q2 [q0q1] -
DFA:
δ a b
qo q1 q2
q1 - q0
q2 [q0q1] -
[q0q1] q1 [q2q0]
