The present application belongs to the technical field of optimization method, and particularly relates to a combined optimization method and device, computer equipment and storage medium. The method comprises: constructing a combined optimization environment model; constructing a stage-aware double-network intelligent agent; using a proximal policy optimization algorithm to perform end-to-end joint training on the double-network intelligent agent, so that the design policy network and the control policy network evolve in a unified optimization framework; during the joint training process, for the magnetization configuration generated by the design policy network sampling, the control policy network performs multiple control evaluations and aggregation to serve as a performance evaluation signal of the magnetization configuration. The present application realizes deep collaborative optimization of magnetic robot form design and control optimization, not only enables the magnetization configuration parameters to be adjusted based on the magnetic field control signal feedback, but also enables the control policy network to adapt to the changes of the magnetization configuration in real time, thereby significantly improving the overall task performance and optimization efficiency of the magnetic robot.

The application discloses a kind of based on partial quantification's hybrid expert network optimization method, it is related to information technology field, including the following steps: S1, selected data sample set, carries out hybrid expert network sampling;S2, establishes the corresponding relationship of subnet and data set, selects high-frequency subnet and corresponding data set;S3, with corresponding data set to selected high-frequency subnet is iterated quantization processing.The application obtains the corresponding relationship of different data set and different subnet in hybrid expert network by carrying out data flow sampling to the reasoning process of hybrid expert network, then carries out quantization optimization to different subnet on corresponding data set, to reduce the calculation burden required for the overall optimization of hybrid expert network, to improve the service throughput of entire network.The data set corresponding to the subnet used frequently is used to carry out quantization processing on the subnet, i.e.to avoid quantization processing on the entire network, simple and efficient, improve the performance of entire network.

The invention relates to the field of block chains, and discloses a lightweight extensible BFT protocol method suitable for a sleep model, and the method comprises the following steps: S1, generating a temporary block sequence; in the step S1, the provisional block sequence comprises the following steps: S11, through a local lot drawing mechanism based on a verifiable random function VRF, selecting a proposal, and generating and broadcasting candidate blocks; s12, performing multiple rounds of communication with a random subset of the node to achieve a provisional consensus for the candidate blocks, and adding the candidate blocks achieving the provisional consensus into the provisional block sequence; and S2, executing a final determination protocol through a final determination committee, processing the temporary block sequence, and outputting a final determination block. By adopting a limited number of block proposals, a pre-consensus mechanism based on network sampling and a constant-scale final determination committee, the communication overhead under a thousand-node scale is reduced, and the method can be efficiently expanded to a larger-scale network.

The application provides a point cloud sampling method for perceptual reconstruction, comprising the following steps: S1, point cloud sampling network sampling: a residual block based on graph convolution is used for local feature extraction of the point cloud, and the sampled point cloud is obtained through mapping according to the point cloud features; S2, point cloud up-sampling network recovery perception: the sampled point cloud is up-sampled to obtain the point cloud data after perceptual reconstruction; S3, point cloud classification network identifies the up-sampled point cloud: the point cloud data after perceptual reconstruction is input into the point cloud classification network, and the training of the point cloud sampling network and the point cloud up-sampling network is supervised through the point cloud classification network. The method can obtain the sampled point cloud which is easier to recover perception.
