Some heuristic methods to use these don’t cares, when an optimization algorithm such as genetic algorithm is used, are also presented. We show that, these methods decrease the quantum cost of the reversible or quantum logic circuit, as well as the design time of the resulting circuit. Some examples are also synthesized and optimized using the don’t care concept and genetic algorithms.
