Comparison
Output values :
- A Mealy machine is determined both by its current state and by the values of its inputs.
- A Moore machine is determined solely by its current state.
The number of states in a Moore machine will be greater than or equal to the number of states in the corresponding Mealy machine. This is due to the fact that each transition in a Mealy machine can be associated with a corresponding, additional state mapping the transition to a single output in the Moore machine, hence turning a possibly partial machine into a complete machine.

- for a Moore machine associates an output value with each state
- for a Mealy machine associates an output value with each transition edge

Famous quotes containing the word comparison:
“Envy and jealousy are the private parts of the human soul. Perhaps the comparison can be extended.”
—Friedrich Nietzsche (1844–1900)
“From top to bottom of the ladder, greed is aroused without knowing where to find ultimate foothold. Nothing can calm it, since its goal is far beyond all it can attain. Reality seems valueless by comparison with the dreams of fevered imaginations; reality is therefore abandoned.”
—Emile Durkheim (1858–1917)
“Most parents aren’t even aware of how often they compare their children. . . . Comparisons carry the suggestion that specific conditions exist for parental love and acceptance. Thus, even when one child comes out on top in a comparison she is left feeling uneasy about the tenuousness of her position and the possibility of faring less well in the next comparison.”
—Marianne E. Neifert (20th century)
