Abstract:

Aiming at the defects of krill herd algorithm and quantum evolutionary algorithm, a quantum krill herd fusion algorithm (QKH) is proposed. The algorithm uses double-chain real numbers to encode the krill position, which can speed up the convergence speed, and avoids the randomness and complexity of quantum observations. The dynamically adjusted quantum krill herd rotation phase update strategy improves the convergence accuracy, and the efficiency of determining the quantum rotation phase. The introduction of an improved quantum full interference crossover strategy can prevent the fusion algorithm from falling into a local optimum, and can improve the optimization efficienal. The advantages of the quantum krill herd fusion optimization algorithm are verified by the classic test functions. A QKH-BPNN prediction model is established for air conditioning load forecasting, and the results show that the model has better accuracy and higher stability.

Key words: quantum krill herd fusion algorithm, double-chain real numbers encoding, quantum krill herd rotation phase, improved quantum full interference crossover, QKH-BPNN prediction
