Retraction Note to: Influence of soil-rock mixture and basketball endurance training management based on virtual network mapping

Abstract

A reasonable virtual network mapping should take into account the heterogeneity of the computing environment and the diversity of virtual network resource requirements to achieve the goals of load balancing between computing nodes and minimizing remote communications. In response to this problem, this paper focuses on the optimization of mapping methods that take into account the heterogeneous computing environment and the diversity of virtual networks. This paper uses indoor physics experiments and discrete element software PFC2D to study the impact of soil-rock mixture and basketball endurance training management and obtain the direct shear characteristics of normal pressure, rock content, rock shape, and maximum rock size on soil samples. It provides an important reference for the analysis of the influence of soil-rock mixture and the management of basketball endurance training. Construct a multi-scale numerical model to study the influence of rock shape and maximum rock size on the shear characteristics and particle crushing characteristics of the soil-rock mixture. The shape of the rock has little effect on the shear strength of the soil-rock mixture; with the increase of the shape coefficient of the rock, the particle crushing rate gradually decreases. The tactical system of basketball is changeable. In a basketball game, the rapid conversion of offense and defense, high-intensity physical confrontation, high-intensity, rapidness, high accuracy, and long exercise time require every athlete not only to have the characteristics of solid basic skills but also excellent physical confrontation ability and excellent physical fitness, and endurance quality is one of the best criteria for evaluating athletes’ physical fitness.
