This invention provides a method, apparatus, device, and storage medium for multi-branch parallel simulation and decision optimization based on a large language model. It constructs a dynamically evolving battlefield state space by receiving multi-source real-time situational data. Situational analysis identifies battlefield emergencies, which are then used as triggers to invoke the large language model to generate multiple differentiated decision branches, each containing macro-level objectives and micro-level strategies. For each decision branch, an independent parallel battlefield simulation instance is constructed and allocated computational and simulation resources, driving synchronous parallel simulations to obtain real-time simulation states. Multi-dimensional dynamic evaluation is performed to obtain a dynamic comprehensive score. Based on this, branches with scores continuously below a preset threshold are dynamically pruned, and their released computational and simulation resources are weighted and redistributed to surviving branches to improve their solution accuracy. Finally, high-scoring, high-quality branches are extracted, and the large language model is invoked to perform decision fusion on their key action sequences, outputting the optimal combat path and command sequence.

The present scheme is connected between plug and socket by lock rod assembly and identification switch effectively.

The utility model discloses an embossing composite roller set, which comprises a main roller and at least two groups of auxiliary rollers which are circumferentially staggered and tightly clung to the roller surface of the main roller, a preset paper web sequentially penetrates through a roller surface gap between the main roller and each auxiliary roller to be subjected to counter-pressing treatment, at least one negative pressure suction section is arranged on the roller surface of the main roller, and the negative pressure suction section is arranged on the roller surface of the main roller. Any negative pressure suction section periodically rotates into an axial surface area between any two adjacent auxiliary rollers along with the rotation of the main roller to apply a negative pressure effect on the paper web, so that the paper web is tightly attached to the roller surface of the main roller; the method has the advantages of low cost, low manufacturing and processing difficulty, more stable and reliable texture pattern formation and the like.

The present invention relates to the technical field of municipal engineering shaft construction, and specifically to a small-diameter rectangular-section shaft excavation device suitable for hard rock, comprising a crawler main machine, the crawler main machine is connected to a rigid frame through a twisted rope and a suspension system, a motor is arranged inside the rigid frame, a main shaft is fixedly connected to the output shaft of the motor, and a three-cone drill bit is connected to the lower end of the main shaft. The beneficial effect of the present invention is that the crawler main machine drives the rigid frame to move to the desired position, and the lifting of the rigid frame is realized through the twisted rope and the suspension system. When excavating, the rigid frame as a whole moves slowly downward, and the motor drives the three-cone drill bit to rotate through the main shaft. The three-cone drill bit first excavates a cylindrical surface for the rock body to be excavated; then the high-pressure air pump works to make the edge crushing device work to crush and excavate around the cylindrical surface, so that a rectangular surface can be formed, which solves the problem of small-diameter rectangular-section shaft construction in existing square pile construction.
