The algorithm first decomposes the original waveform into three layers, and uses the improved absolute value difference method, the improved sequence similarity method, and the normalized cross-correlation method for matching in each layer, and finally achieves accurate matching. Fantasy Skyline brings together his life's creative approach and presents it with great maturity, with a bright and smooth melody in its structure. The entire musical composition contains more than 40 poems and is named after 14 of them. The creation of the works not only contains the passion and fantasy in the verse, but also is full of many profound irony. The search strategy of the hill-climbing method and the particle swarm optimization algorithm of the swarm intelligence algorithm are respectively used to realize the non-traversal search of the waveform matching algorithm.
