Fig. 8From: PP-DDP: a privacy-preserving outsourcing framework for solving the double digest problemThe flowchart of QIGA. The input instances are the ciphertexts encrypted by the order-preserving homomorphic index scheme, after calculating the fitness value, if not satisfied with the stop condition, the quantum crossover and quantum mutation operators will be performed and generated new offsprings. Otherwise, output the optimal resultsBack to article page
