This invention discloses a three-dimensional pipeline path design method and system based on discretized string representation and optimization. It establishes a globally fixed world coordinate system and a locally updated coordinate system that dynamically updates with construction operations. The continuous initial three-dimensional pipeline path space in the world coordinate system is discretized and converted into a world string. A multi-objective optimization algorithm is used for iterative optimization to generate a set of optimized schemes containing multiple path heterogeneities.

This method has very high computational efficiency, can generate multiple technical solutions and obtain a globally optimal topology, and can directly generate construction instructions from the optimal solution.

This application discloses a method for training an encoding / decoding model, a computer device, and a computer storage medium. By introducing a dual-path design that separates the main encoding structure and the detail encoding structure, differentiated encoding of the main information and detail information in the audio signal is achieved. The main encoding structure focuses on processing the raw spectral data that carries the basic outline and core content of the audio, ensuring accurate capture and efficient encoding of the main information; the detail encoding structure is specifically designed for fine processing of the detail spectral data extracted from the raw spectrum, focusing on preserving subtle features that are crucial to the auditory experience, such as high-frequency overtones, transient changes, and weak environmental noise. This clearly defined structural design avoids the problems of insufficient learning or overfitting that easily occur when a single encoding path processes a large amount of main and detail information simultaneously at high bit rates, thereby effectively reducing the "illusion" phenomenon caused by insufficient learning of detail information or scarcity of training data.
