How do you construct the union of two DFA's?
问题 Does anyone have a straightforward description of the algorithm for constructing the union of two given DFA's? For example, say we have two DFA's over {0,1} where {w|w has an odd number of characters} w has states A and B delta | 0 | 1 ---------------- A | B | B ---------------- B | A | A {x|x has an even number of 1s} x has states a and b delta | 0 | 1 ---------------- a | a | b ---------------- b | b | a I have a resulting transition table showing the union as: delta | 0 | 1 ---------------
